Appellants Mervyn Harold Cross and Robert Carter Lodge were each indicted in November 1984 by a federal grand jury in Tampa, Florida, on one count of conspiracy to persuade a minor to engage in sexually explicit conduct for the purpose of producing visual or print media, 18 U.S.C.A. §§ 371 (1966) and 2251 (1982); one count of mailing obscene material, 18 U.S.C.A. § 1461 (1984); and 18 counts of mail fraud, 18 U.S.C.A. § 1341 (1984). After a jury trial, Cross was convicted on all counts with the exception of one count of mail fraud, and Lodge was found guilty on only the conspiracy charge.
The evidence at trial showed that between 1980 and 1983, Cross and Lodge, together with co-defendant Ruksana Di-wan, conspired to exploit children sexually in order to produce and sell child pornography. 1 Cross, while a prison inmate in Florida, orchestrated a fraudulent scheme to obtain nude photos of child models from the Tampa, Florida area by falsely portraying himself as a film producer and misrepresenting that the pictures were necessary for casting decisions for a legitimate educational documentary. Lodge, who, like Cross, was a pedophile interested in pre-ad-olescent girls, used a lab in his Seattle, Washington home to develop these pictures as well as obscene photos of two California children which Cross arranged for him to receive in the mail. Diwan assisted by placing telephone calls, directing mail, and serving as a Florida contact for Cross.
Cross and Lodge have appealed their convictions on a multitude of grounds: co-conspirator hearsay, immunity, denial of a continuance, prosecutorial misconduct, sufficiency of the evidence, improper jury instructions, unduly prejudicial evidence, recanted testimony, a false search warrant affidavit, and refusal to sever. 2 We now affirm. 3
*1035 BACKGROUND
Cross and Lodge began their association, in 1975 when Lodge responded to an advertisement by Cross’s mail order company, “Cine International,” offering “erotic” photographs of children. Cross and Lodge soon started to exchange such pictures and share accounts of their sexual experiences with children. In 1978, the two men, through letters and phone calls, began to discuss a series of proposed ventures for producing and marketing child pornography. Cross offered to arrange several opportunities for Lodge to take sexually explicit photos of pre-adolescent girls. In return, Lodge would process the film and send the pictures to Cross, who would sell the photos and share the profits with Lodge. Lodge expressed to Cross his interest in several of these ventures and at least one such photo session was arranged but had to be cancelled at the last minute when a woman, whose two young daughters Lodge had intended to pay to pose nude, telephoned Lodge’s home and mistakenly mentioned the plan to Lodge’s wife.
In 1980, Cross recruited Lodge for a scheme that involved sending obscene materials through the mail. Several years earlier, Cross had begun communicating with Elmer Donald Woodward concerning “their mutual interest in child pornography.” 4 On several occasions, Woodward mailed to Cross the negatives of obscene photographs of a seven-year old California girl and her younger brother. Cross indicated to Woodward that Lodge could develop the pictures for a reasonable fee, and offered to pay for the film processing himself if he also could receive a set of prints. Cross subsequently arranged for his attorney to mail the Woodward negatives to Lodge. Both the negatives and black and white prints of the photos were later discovered during a search of Lodge’s home in May 1983.
In 1981, Cross and Lodge, this time with Diwan’s assistance, initiated a new attempt to obtain nude photographs of children and market them as child pornography by means of an elaborate confidence game in which the parents of child models in the Tampa, Florida area were misled into believing that Cross was an independent movie producer who required such pictures in order to make casting decisions for a new film. 5 Using a dummy corporation as a front, Cross contacted a Tampa talent agency, and requested and received composite photographs and resumés of actresses between the ages of eight and twelve. 6 Cross informed the head of the agency that he was looking for a young girl to star in an educational documentary he was producing, and indicated that because it might involve some nudity, the agency should inform him as to which children did not suffer from “modesty problems.” 7
Cross contacted the parents of several of the agency's models, 8 and later enlisted a *1036 professional photographer in Tampa to take “casting” pictures of these young girls. 9 Cross instructed the photographer to shoot several nude photos of the girls, allegedly in order to gauge their reactions to being filmed in the nude, and to determine whether the models were too physically developed to play the role of a young child. Cross further directed the photographer to provide him with full frontal nude pictures in the form of color transparencies three times the size of normal slides. 10 Like the talent agency, both the photographer and the girls’ parents were told by Cross that the photo sessions were necessary because the film would include scenes in certain locations where native people routinely wore little or no clothing. Cross also assured them that these photos would not be reproduced and would be returned to the parents.
However, soon after receiving the transparencies, Cross mailed them to Lodge to be processed and enlarged so they would be suitable for sale. Lodge developed and sent to Cross slides from some of these transparencies, but indicated that several of the other pictures would need to be retaken because of their inferior quality. 11 When Lodge’s house was searched in May 1983, police discovered a negative strip containing a sequence of nude, black and white photos of one of the Tampa girls. 12 In addition, the strip contained versions of these photos that Lodge had cropped to highlight the girl’s nude torso, followed by closeup photographs of adult female genitalia which he had added.
Neither Cross nor Lodge testified at trial. Cross, who represented himself, called several law enforcement officers and fellow prisoners to testify, in an attempt to show that he had planned and engaged in these various child pornography schemes in the course of acting as a police informant. Two character witnesses testified on Lodge’s behalf.
DISCUSSION
I. SEVERANCE
Lodge contends that he was deprived of his right to a fair trial as a result of being tried jointly with his co-defendant Cross. Lodge argues that the district court erred in summarily denying his pre-trial motions for severance, and that he was unfairly prejudiced by a joint trial. 13 He advances three grounds in support of this claim of error: (1) that Cross would have provided exculpatory testimony on Lodge’s behalf had their cases been severed, (2) that Lodge’s and Cross’s defenses at trial were antagonistic, and (3) that Cross’s behavior during the trial and evidence introduced solely against him had a prejudicial spill *1037 over effect on the jury’s determination of Lodge’s guilt.
As a general rule, defendants who have been jointly indicted should be tried together, particularly in conspiracy cases.
United States v. Castillo-Valencia,
A. Exculpatory Evidence
Lodge argued to the district court in his motions for severance that if he and Cross were tried separately, Cross would provide exculpatory testimony on Lodge’s behalf. In support of this contention, Lodge submitted an affidavit from Cross, in which Cross promised to testify “if I can do so without exposing myself to criminal jeopardy in [this] case,” and described his proposed testimony. In his affidavit, Cross stated that Lodge had neither known of nor participated in the Tampa photo arrangements, but had “inadvertently” been mailed these photographs; that he and Lodge had otherwise never exchanged child pornography but only “naturist photographs” of the kind found in “nudist magazines;” and that he had communicated with Lodge as a police informant surreptitiously seeking information about illegal activities. Lodge now contends that Cross’s testimony could have refuted the government’s conspiracy charge against him. 14
In order to warrant severance based on a co-defendant’s potential testimony, an accused must first show: “(1) a bona fide need for the testimony; (2) the substance of the desired testimony; (3) the exculpatory nature and effect of the desired testimony; and (4) that the codefendant would indeed ... testif[y] at a separate trial.”
United States v. Funt,
We are not persuaded as to the exculpatory nature or effect of Cross’s proposed testimony. The affidavit consisted of little more than bare conclusory assertions of Lodge’s lack of involvement, and contained no clear indication of any “specific and exonerative facts” to which Cross would have testified.
United States v. Pepe,
B. Antagonistic Defenses
A defendant is not entitled to a trial separate from that of his co-defendant simply because their defenses are prejudicial to one another. Rather, a trial court abuses its discretion in denying a severance only when the defenses advanced are “so antagonistic as to be irreconcilable or mutually exclusive.”
United States v. Castillo-Valencia,
C. Prejudicial Spillover
Finally, Lodge claims that his conviction should be reversed because his joint trial with Cross created a prejudicial spillover effect on the jury’s determination of Lodge’s guilt. Lodge contends that Cross’s misbehavior as a pro se litigant and the government’s introduction of inflammatory evidence against Cross deprived Lodge of his right to a fair trial. 20 We find that this theory, like Lodge’s other grounds for challenging the denial of severance, is without merit.
As the court has noted, denial of severance will be considered error where the defendant can demonstrate that he suffered “compelling prejudice” as a result of the spillover effects of being tried jointly with a co-defendant. The applicable test is whether it was “within the capacity of [the] jurors to follow [the] court’s limiting instructions and appraise the independent evidence against each defendant solely upon that defendant’s own acts, statements, and conduct.”
21
United States v. Silien,
II. SEARCH WARRANT
Lodge also contends that the district court erred in failing to conduct a pretrial evidentiary hearing on his motion to suppress evidence seized during a search of his Seattle home in May 1983. At trial, Lodge argued that Detective Thomas Dittmar of the Seattle Police Department intentionally or recklessly included false information and misleadingly omitted material facts from his search warrant affidavit. The district court, however, found that even if the allegedly false or misleading statements were deleted or corrected, the affidavit was still sufficient to establish probable cause for the search of Lodge’s house. Relying on our independent weighing of the allegations in such a redacted affidavit, we too conclude that the Seattle judge who issued the search warrant had a “substantial basis” for finding that probable cause existed.
See United States v. Sims,
In
Franks v. Delaware,
In this case, Dittmar’s affidavit contained information that he received from William Dworin, a Los Angeles police detective who had corresponded with Lodge in the course of an undercover investigation of child pornography. 25 In a then-recent letter to Dworin, Lodge had stated that he was “fairly active in photography,” had a collection of “15,000 to 20,000 negatives,” and had “contacts that may eventually lead to some good models.” Lodge had also indicated that he had “a fair amount of European material, but as you know acquisition has been difficult lately.” Lodge assured Dworin that it would be “safe” to send him “any mail of any type.” In addition to providing the Seattle detective with a copy of Lodge’s letter, Dworin also informed Dittmar that Lodge’s name had appeared on Cross’s mailing lists for child pornography when he arrested Cross several years earlier. Finally, Dittmar’s affidavit also contained certain information about Lodge’s involvement in the Tampa photo hoax. According to the affidavit, the source of this last material was a government official who, in turn, had learned of the conspiracy from Cross.
Lodge argues that the following “facts,” which he presented to the district court, constituted a “substantial preliminary showing,” mandating a pretrial hearing on his suppression motion: (1) Dittmar failed to contact Cross to verify Lodge’s involvement in the Tampa scheme; (2) Cross denied making the statements attributed to him in the affidavit; (3) Dittmar failed to disclose that such information actually came from several prisoners incarcerated with Cross, whose reliability was unproven; and (4) the affidavit did not describe or *1041 attach the letter from Dworin which elicited Lodge’s return correspondence.
We assume, as did the district court, that Cross has satisfied the first prong of
Franks
by alleging, in more than conclusory fashion, a deliberately or recklessly false statement or material omission from the affidavit. However, even if all the information attributed to Cross were removed and the letter from Dworin to Lodge were added, the redacted affidavit would still contain allegations sufficient to support a finding of probable cause.
See Jenkins,
III. SUFFICIENCY OF THE EVIDENCE
A. Lodge
In his third and final claim of error, Lodge challenges his conviction of conspiracy to exploit a minor sexually, on the ground that the evidence introduced against him at trial was insufficient as a matter of law to sustain a guilty verdict on this charge. In evaluating the sufficiency of evidence, we must view the evidence and all reasonable inferences that may be drawn from it in the light most favorable to the government.
29
Glasser v. United States,
Lodge was convicted, under the federal conspiracy statute, 18 U.S.C.A.
*1042
§ 371 (1966), of conspiring with Cross and Diwan to sexually exploit children in violation of 18 U.S.C.A. § 2251(a) (1982).
30
This latter section, as it existed at the time of Lodge’s offense, applied to “any person who employs, uses, persuades, induces, entices, or coerces any minor to engage in any sexually explicit conduct for the purpose of producing any visual or print medium depicting such conduct ... if such person knows or has reason to know that such visual or print medium will be ... mailed, or if such visual or print medium has actually been ... mailed.” 18 U.S.C.A. § 2251(a) (1982).
31
Lodge now contends that the evidence at trial failed to prove the elements of a conspiracy under § 371. To support a conviction for conspiracy, the prosecution must prove that two or more persons agreed to commit a crime, that the defendant knew of the conspiracy, and that he voluntarily participated in helping to achieve its objective.
United States v. Roper,
The evidence presented by the government amply demonstrated both the existence of, and Lodge’s knowing involvement in, a conspiracy with Cross and Di-wan to produce and market child pornography. The correspondence between Cross, Lodge, and third parties, as well as altered versions of the Tampa photos found in Lodge’s home, make clear that Lodge knew of Cross’s and Diwan’s plan to deceive the models and their parents into providing nude pictures, and that Lodge actively participated in the scheme by processing and modifying these photos in order to render them suitable for commercial distribution. The proof at trial was more than adequate to support Lodge’s conviction. 33
B. Cross
Cross also argues that the evidence at trial was legally insufficient as to the conspiracy charge of which he too was found guilty. Cross alleges not that the government failed to prove all the elements of a conspiracy; rather, he contends that his conviction should be reversed because the evidence did not demonstrate that the Tampa photos were obscene, or that he endeavored to produce them for pecuniary gain. However, the antecedent version of 18 U.S.C.A. § 2251, which Cross was convicted of violating, did not require that either the “sexually explicit conduct” engaged in by the minor or the “visual or print medium” created from that conduct be obscene.
34
See
18 U.S.C.A. §§ 2251(a), 2253(2) (1982);
New York v. Ferber,
458
*1043
U.S. 747, 762 n. 15,
IY. JURY INSTRUCTIONS ON MAIL FRAUD
Relying on the Supreme Court’s decision in
McNally v. United States,
In disposing of an appeal by Cross’s co-defendant, Diwan, this court has already determined that the indictment in this case sufficiently alleged a plot to deprive the victims of property or money.
41
See United States v. Diwan,
One objective of this conspiracy ... was that the girls forfeit modelling services, photographs, and the likenesses that emanate therefrom. The photographer would lose the value of his services, as would the ... [tjalent [ajgency ... the photographer would necessarily have to use film and other materials in producing the photographs, and [the talent agency] would forfeit proprietary business information — the identities and the addresses of aspiring actresses. All of these items have value to the owner.
Id. at 719. Nevertheless, Cross now argues that the evidence presented at trial and the jury charge on the elements of mail fraud allowed the jury to convict him of engaging in a deception involving intangible, McNally-type rights. In attempting to identify such rights in this case, which were unprotected by the mail fraud statute, Cross contends that his guilty verdict may have improperly rested on proof showing only that he sought to obtain the Tampa photographs to satisfy his own sexual appetites.
Cross is wrong on all accounts. The evidence at trial proved the indictment’s allegations of losses suffered by the victims, as described in
Diwan.
More importantly, the district court’s instructions specifically directed the jury that it could return a guilty verdict on the mail fraud counts only if it found that Cross had devised “a scheme to defraud or for obtaining money or property,” and defined scheme to include any plan to obtain “money or property.”
See Dynalectric,
Diwan misses the point when she argues that the primary objective of the scheme was merely personal sexual indulgence, and not the deprivation of property through fraud. The entire array of deprivations announced in the indictment would be a necessary result of the overt acts planned to further the scheme. If the defendants were to achieve success in their endeavor in the chosen manner, *1045 the girls, the photographer, and the talent agency would have to lor :, and what they would lose is property.
Diwan,
V. ADMISSION OF CROSS’S LETTERS TO LODGE
A. Immunity
As the centerpiece of his defense at trial, Cross sought to prove that, in corresponding with Lodge, he was acting as an informant for the Florida Department of Law Enforcement under an official grant of immunity. Cross claims that his convictions should be overturned because the trial court improperly admitted as evidence letters that he wrote to Lodge as part of his work on behalf of a government investigation of child pornographers.
44
For the purposes of resolving this issue, we accept, as did the district court, Cross’s contention that such evidence would be subject to exclusion if it were indeed a product of either an actual immunity agreement or Cross’s good faith belief that he had been granted immunity from prosecution.
See United States v. Harvey,
In 1979, Cross, through his attorney, Raymond Cramer, contacted the Florida Department of Law Enforcement to ex *1046 plore the possibility of assisting the Department in an investigation of child pornography distribution. In 1980, Cross, Cramer, and Department agent Michael Brick met on several occasions to discuss ways in which Cross could aid in the investigation, but no agreement was reached. Brick suggested that Cross maintain his contacts with pornography distributors, but not with individual pedophiles. Brick also instructed Cross to mail only written materials, and specifically rejected a proposal by Cross that he send out a fake brochure containing pictures of nude children. 48 Later that year, Department agent George Syring, who had been reassigned in Brick’s place, together with United States Postal Inspector Ted Griem also contacted Cross in order to solicit his assistance in gathering information about child pornographers. At a meeting with Cross in 1981, Syring and Griem instructed him to correspond with four magazine advertisers, who they suspected were peddling child pornography, through a post office box rented by Syring under a false name. No letters to or from Cross were ever received at this post office box. Instead, Cross asked the Department for a grant of immunity before proceeding with any correspondence. Several months later, the Department’s legal counsel forwarded a draft immunity agreement to Cross which he signed and returned to the Department through his attorney, Cramer. 49 The agreement was never signed by any law enforcement official and was never returned to Cramer or Cross. 50 Cramer testified that he assumed that the Department’s failure to return the immunity agreement meant that they had decided not to go forward with it. 51
What is most telling is that, contrary to his instructions, Cross never informed any of the government officials with whom he communicated during this period about the Tampa photo scheme or that he was mailing nude pictures, nor did he ever receive permission from any law enforcement officer to engage in such activities. 52 Indeed, Cross’s intrigues involving the child models occurred in late 1982 and early 1983, well after he had last had any discussions with or received any news from law enforcement officers concerning his assistance in an investigation or the possibility that he *1047 would be granted immunity. In short, based on these facts, it was not unreasonable for the jury to find that Cross did not engage in these activities under a good faith belief that he was acting on behalf of law enforcement and under a grant of immunity. 53 Clearly rather, Cross was, as the government aptly describes it, “playing both ends against the middle in a cynical effort to create a defense for himself if his efforts to obtain pornographic pictures of little girls were discovered.” 54
B. Relevancy and Undue Prejudice
In addition to challenging the admission of his correspondence with Lodge on the basis of his purported immunity agreement, Cross also claims that the letters should have been excluded because they were unduly prejudicial and because those which predated the conspiracy were irrelevant to the charges against him. A district court’s admission of “extrinsic act” evidence under Federal Rule of Evidence 404(b) will not be reversed absent an abuse of discretion.
55
United States v. Jones,
Cross, however, also contends that even if the correspondence were relevant,
*1048
the probative value of these and other, post-1980 letters used against him by the government was substantially outweighed by their unfair and unduly prejudicial impact on the jury.
See
Federal Rule of Evidence 403.
59
Cross points, in particular, to some of the letters’ sexual references to children, and argues that their admission created an unacceptable risk that the jury convicted simply because he was a pedophile. A conviction will not be set aside because of a district court’s refusal to exclude evidence under Rule 403 absent a clear abuse of discretion.
Cauchon v. United States,
VI. REFUSAL TO GRANT A CONTINUANCE
Cross insists that he is entitled to a new trial as a result of the district court’s refusal to grant a continuance to enable him to call his daughter as a witness. The decision whether to continue a trial is committed to the sound discretion of the district court.
United States v. O’Neill,
Cross’s claim fails to satisfy several of these criteria. First, Cross was not diligent in endeavoring to secure his daughter’s presence, and did not demonstrate that she would actually be available to testify within a reasonable period of time. He first indicated to the trial court that he was *1049 having difficulty locating his daughter, who lived in Canada, two weeks after he had begun to present his defense, on the day he rested his case. At such time, the court granted Cross a five-day continuance, indicating that he would be allowed to reopen his case during or after Lodge’s defense in order to call his daughter as a witness, but that if she were not available on that date, the trial would be completed and the case submitted to the jury. On the day that Cross’s daughter was supposed to appear, he moved for another continuance on the ground that she had been forced to remain in Canada to care for a sick relative. Cross did not specifically indicate to the court when his daughter would be available to testify. 62 Refusing to further delay the trial, the court denied Cross’s motion.
Second, his daughter's testimony would have been, at best, cumulative and of marginal benefit to Cross’s defense. Cross contends that she would have testified that he had, in the 1950’s and 60’s, been a legitimate film producer and had intended to produce a documentary similar to the one that was the subject of the Tampa hoax. Such evidence, however, would have been of little relevance to the question of whether, decades after the events claimed by his daughter, Cross obtained nude photos from the young models in order to create child pornography. Indeed, the evidence at trial that Cross’s activities were not aimed at producing a legitimate film was overwhelming. Moreover, two other witnesses, the head of the talent agency and the Tampa photographer hired by Cross, each testified that he indeed demonstrated a professional familiarity with the film business and appeared to be a knowledgeable, experienced producer. The district court did not abuse its discretion in refusing to grant Cross a second continuance.
VII. EXPERT TESTIMONY
Cross next argues that he is entitled to a new trial because the district court erred in admitting irrelevant, cumulative, and unfairly prejudicial expert testimony by Kenneth Lanning, an FBI agent, on the characteristic behaviors of pedophiles. A trial court has wide discretion in determining whether to exclude expert testimony, and its action will be sustained on appeal unless “manifestly erroneous.”
United, States v. Burchfield,
In regards to the California photos that were the subject of Count II of the indictment, Lanning testified that these pictures would be of sexual interest to pedophiles and offered his expert opinion that they were obscene. Count II charged both Cross and Lodge with mailing obscene material in violation of 18 U.S.C.A. § 1461
*1050
(1984), and the obscenity of these photos was an essential element of the offense. It is well settled that such expert testimony is permissible in an obscenity prosecution, particularly when “contested materials are directed at ... [such] a bizarre deviant group that the experience of the trier of fact would be plainly inadequate to judge whether the material appeals to the prurient interest.”
Bagnell,
Lanning's testimony was also helpful to the jury and relevant to its consideration of the conspiracy and mail fraud charges against Cross. In his defense at trial, Cross contended that the Tampa photos were innocent “nude studies,” rather than child pornography, and that he had arranged them for the purpose of casting a legitimate film. In describing the habits of pedophiles, Lanning testified that such persons characteristically derive sexual satisfaction from and collect even such ostensibly non-sexual nude photographs of children. Lanning also told the jury that these kinds of pictures, rather than more graphic ones, are frequently published in magazines distributed to pedophiles in an attempt to circumvent laws against obscenity and child pornography.
65
Such evidence clearly shed light on one of the critical issues in the case — whether Cross obtained the photos with the intention of using them to produce and distribute child pornography. Indeed, federal courts have ordinarily allowed law enforcement officials “to testify as experts ... to establish the
modus operandi
of particular crimes,” in order to “explain the actions of the defendants.”
66
Burchfield,
Cross, however, also insists that even if Lanning’s testimony were relevant and helpful to the jury, it should nevertheless have been excluded under Federal Rule of Evidence 403 because its probative value was substantially outweighed by its undue prejudice and tendency to mislead the jury.
See Rouco,
VIII. CO-CONSPIRATOR HEARSAY
In his initial pro se brief, Cross complains that the district court improperly admitted certain hearsay statements made to law enforcement officers by Diwan and Lodge. At trial, a prison inspector and state police official from Florida each testified that Diwan provided and identified for them certain documents that the government later introduced as exhibits at trial, including a package of nude photographs which Diwan indicated she had received from the Tampa photographer. In addition, Seattle Detective Thomas Dittmar also testified that at the time he and other officers searched Lodge’s home, Lodge acknowledged to him that he collected child pornography, knew Cross, and that the dummy corporation created as a front for the Tampa photo scheme had been Cross’s idea.
An out-of-court statement by a co-conspirator is admissible under both Federal Rule of Evidence 801(d)(2)(E)
70
and the
*1052
Confrontation Clause of the Sixth Amendment if the trial judge determines that the government has proven by a preponderance of the evidence that (1) “the declarant and the defendant were involved in an existing conspiracy,” and (2) “the statement was made in furtherance of that conspiracy.”
71
United States v. Jones,
However, this conclusion does not end our inquiry. It is well-established that the improper admission of co-conspirator hearsay, like other Confrontation Clause errors, is subject to the harmless error rule of
Chapman v. California,
IX. RECANTED TESTIMONY
Cross contends that Warren Mum-power, a former fellow inmate and government witness, has since recanted the testimony he gave at Cross’s trial.
74
However, the proper procedure for presenting such newly discovered evidence would have been to file a motion for a new trial in the district court.
See
Fed.R.Crim.P. 33. Cross has failed to pursue this avenue and it is now closed to him, as the prescribed two-year period in which to move for a new trial under Rule 33 has expired.
75
This court cannot consider a claim that rests on factual allegations outside the record which the district court has never considered.
See United States v. Costa,
X. PROSECUTORIAL MISCONDUCT
We now dispose of Cross’s final claim that he is entitled to a new trial because the prosecution improperly obtained his sealed witness list, and colluded with Diwan’s defense counsel to induce her to flee the country.
77
As a general matter, we will reverse a conviction on the basis of governmental misconduct only if the misconduct may have prejudiced substantial rights of the accused.
United States v. Collins,
As for the other element of Cross's misconduct claim, it is true that government intimidation of defense witnesses can constitute a denial of due process.
See United States v. Terzado-Madruga,
CONCLUSION
Accordingly, the judgment of the district court is AFFIRMED.
Notes
. Diwan was also indicted for conspiracy and mail fraud and was originally scheduled to be tried jointly with Cross and Lodge. However, she failed to appear for trial. Diwan was eventually extradited from England and entered a conditional guilty plea in October 1987. This court affirmed her conviction.
United States v. Diwan,
. Cross filed his initial appellate brief in this court pro se. However, subsequently, an attorney was appointed to represent him and filed a supplemental brief. We address the issues raised in each brief.
. We consider separately each of appellants’ claims of error. However, because we find no
*1035
error save for the admission, of certain cocon-spirator statements which we conclude was harmless beyond a reasonable doubt,
see
section VIII of the court’s opinion, we have no occasion to address Lodge’s contention that he was prejudiced by the "totality” of various alleged violations of his constitutional rights.
See Chapman v. California,
. At the time of trial, Woodward was in prison in California, serving sentences for two related sex offenses.
. Cross and Lodge also hoped that this deception might ultimately provide them with an opportunity to molest some of the children.
. Cross, Diwan, and Lodge were officers or directors of this corporation, which Cross named "Viewfinder, Inc.”
. Cross explained that the documentary, to be entitled, "Susan’s Magic Carpet,” would be about a girl who travels around the world, and that, in order for the film to be realistic, the principal character would briefly have to appear nude in certain scenes such as, for example, an aboriginal dance sequence in New Guinea.
. Cross exchanged extensive correspondence with the parents of those girls in whom he was interested and in some cases with the girls *1036 themselves, providing them with widely varying information concerning the storyline and venues for the film, production and travel arrangements, their chances of selection, and the salary each actress would be paid if chosen for the project.
. Because Cross was a prison inmate in Florida during this time, in all his communications with the talent agency, models’ parents, the Tampa photographer, and Lodge, he used Diwan to set up "conference calls” and relay his mail, so as to conceal the fact that he was incarcerated.
. Cross carefully specified the poses in which the children were to be photographed. However, because they were uncomfortable with some of these poses, including one which called for the children to squat on their knees, the photographer and several of the parents did not agree to the shooting of certain nude photos, and the photographer deliberately did a poor job of developing the film so that the pictures he did take could not be copied.
. Around this time, Cross suggested in a letter that Lodge return the original, poor-quality transparencies to him, explaining that he had been able to persuade the girls’ parents to allow another nude photo session, but only on the condition that the first set of pictures be destroyed.
. Also found in Lodge’s home were a number of reproductions of the Tampa pictures that Lodge had arranged to have developed by a commercial photo lab.
. Lodge moved for severance under Federal Rule of Criminal Procedure 14, which provides, in relevant part:
If it appears that a defendant or the government is prejudiced by a joinder of offenses or of defendants in an indictment or information or by such joinder for trial together, the court may order an election or separate trials of counts, grant a severance of defendants or provide whatever other relief justice requires.
. Lodge’s defense at trial can be characterized as an attempt to show that he was, at most, a passive recipient of child pornography from Cross.
. In
Bonner v. City of Prichard,
. "Although considerations of judicial economy cannot be elevated to the point where they impair a defendant’s rights under the Constitution or Fed.R.Crim.P. 14, they are relevant.”
Pepe,
. Because the court finds that Cross’s proffered testimony would have been of insignificant or no benefit to Lodge, we need not reach the issue of whether the affidavit sufficiently demonstrated that Cross would in fact have testified on Lodge's hehalf had their trials been severed. However, we note the Cross’s promise to testify only if he could do so "without exposing [him]self to criminal jeopardy” probably fails to satisfy this requirement.
See Funt,
. In
Stein v. Reynolds Securities, Inc.,
. Cross himself never testified and none of his evidence implicated Lodge.
See United States v. Pirolli,
. During the trial, the district judge frequently admonished Cross, in the presence of the jury, for improper remarks made by him during his cross-examination of government witnesses. In addition, the government presented testimony against Cross describing various pornographic photographs of children, other than those involved in the Tampa photo scheme, which were found in his possession.
. A defendant does not suffer compelling prejudice simply because most of the evidence presented at trial is applicable only to his co-defendant, or because such evidence pertains to the co-defendant’s reputation or criminal record.
United States v. Pritchett,
. Lodge does not allege that the trial court improperly denied any requests for instructions.
. Indeed, much of the cross-examination conducted by Lodge’s counsel focused on carefully distinguishing the evidence against Cross from that against Lodge.
. In
United States v. Leon,
. Dworin wrote to Lodge under the fictitious name, “Pete Davis.”
. This is how the letter was understood by Dittmar, an experienced expert, according to the affidavit, in the investigation of offenses involving child pornography.
. In his unsolicited letter to Lodge, Dworin wrote that a mutual friend had suggested that the two men shared "a common interest,” and went on to note that he was "a firm believer in the liberal upbringing of young girls and have raised my 10-year old girl this way. She has been photographed extensively in her training. I hope to hear from you and exchange experiences. I also have a small collection of European material that you may enjoy.”
. Lodge also argues that "chain of custody problems” aggravated the prejudice he suffered at trial from the introduction of evidence discovered pursuant to the allegedly illegal search of his house. Although items seized from Lodge’s Seattle home were at one time commingled with evidence obtained in Florida, the trial record indicates that law enforcement officials later re-separated the evidence. Moreover, the items of evidence found in Lodge's house were adequately identified by witnesses at trial who testified to their sources and original conditions. The district court did not abuse its discretion in admitting these materials into evidence over Lodge’s chain of custody objections.
See United States v. Burchfield,
.
See also United States v. Morales,
. 18 U.S.C.A. § 371 (1966) forbids any conspiracy to commit an offense against the United States.
. Section 2251, originally enacted in 1978, was amended in 1984 and again in 1986 and 1988. Cross and Lodge, whose crimes occurred between 1981 and 1983, were prosecuted under the original, 1978 version of the statute.
. The government need only show that the defendant was aware of the "essential purpose" of the conspiracy, rather than that he "knew all the details.”
Obregon,
. Lodge also argues that he cannot legally be held to have conspired with Cross because Cross was acting as a police informant. Because we find that Cross’s conduct was not undertaken on behalf of law enforcement officials, see section V(A) of the court's opinion, we also find that Lodge's derivative claim lacks merit.
. Sexually explicit conduct was defined to include “actual or simulated ... lewd exhibition of the genitals or pubic area of any person." 18 U.S.C.A. § 2253 (1982). Neither Lodge nor Cross claim on appeal that the Tampa pictures or the scenes they depicted were not "lewd" within the meaning of the statute; therefore, we do not reach this issue. However, even if they had raised such an argument, we would still affirm their convictions on this count. The
*1043
Tampa photographs displayed pre-adolescent girls fully nude from a frontal view, and were arranged by Cross in order to be used to satisfy the sexual interests of himself and other pedophiles. Moreover, Cross had also ordered that the children be photographed in the nude, squatting on their knees, but the Tampa photographer felt uncomfortable with and ultimately refused to shoot such pictures. Based on these factors, we are of the opinion that the photographs taken or planned involved “lewd exhibition of the genitals or pubic area.” We reach this conclusion despite the obvious fact that the photographs did not portray the models as sexually coy or inviting, and the Tampa photographer who had been duped by Cross did not knowingly or intentionally exhibit the girls in lewd poses.
See United States v. Wolf,
. The Child Protection Act of 1984, which amended § 2251, also removed the obscenity requirement that had previously applied to § 2252, a provision under which Cross was not prosecuted. See 18 U.S.C.A. § 2252 (1989); H.R.Rep. 536, 98th Cong., 1st Sess. at 10—11, reprinted in 1984 U.S.Code Cong. & Ad.News 492, 501-02.
. See 18 U.S.C.A. § 2253 (1982) (defining "producing" to mean "producing, directing, manufacturing, issuing, publishing, or advertising, for pecuniary profit”).
. The district court instructed the jury, pursuant to the statutory definition contained in § 2253, that Cross could only be convicted under § 2251, if he had produced the material in question for “pecuniary profit.”
. McNally was decided after Cross's trial but before he filed his opening brief on appeal. This court permitted Cross to file a motion in the district court to set aside his mail fraud convictions as invalid under McNally. The district court denied the motion.
. The statute provides criminal punishment for,
Whoever, having devised or intending to devise any scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises ... for the purposes of executing such scheme or artifice or attempting to do, places in any post office or authorized depository for mail matter, any matter or thing whatever to be sent or delivered by the Postal Service....
18 U.S.C.A. § 1341 (1984).
The ruling in
McNally
was overridden by the recent enactment of 18 U.S.C.A. § 1346 (1989), which provides that “[f]or the purposes of this chapter [which includes § 1341], the term 'scheme or artifice to defraud’ includes a scheme or artifice to deprive another of the intangible right to honest services.” This later amendment has no application to Cross’s case.
*1044
See Corcoran
v.
American Plan Corp.,
. In
McNally,
the Court held that the mail fraud statute did not apply to schemes to defraud citizens of their rights to honest government.
Id.
at 359,
. Diwan had entered a conditional guilty plea, reserving the right to appeal the district court's denial of her motion to dismiss the indictment.
. The court also instructed that the government had to prove beyond a reasonable doubt that Cross devised a scheme to defraud “substantially the same as the one alleged in the indictment."
. Furthermore, as the court has already discussed, the evidence at trial amply demonstrated that Cross sought the nude photos, at least in part, in hopes of employing them for financial gain. See section III of the court’s opinion.
. Cross also contends that the district court erred in failing to dismiss the indictment’s conspiracy count because it was based on his immunized conduct. Because, as discussed below, we concur with the jury's determination that Cross did not in good faith believe he was acting on behalf of law enforcement when he wrote to Lodge or undertook other actions in furtherance of his pornographic ventures, we conclude that this claim of error, like Cross’s related contention that his correspondence with Lodge was improperly admitted at trial, is without merit.
. Cross complains that the district court should have ruled on his motion to exclude the letters
in limine,
as he had requested, rather than during the trial at the point when the government sought to introduce such correspondence. However, we find that it was proper for the court to reserve decision on Cross’s request. The motion was filed on the eve of an already twice-delayed trial, and resolution of the immunity issue at that juncture would have required a trial-in-miniature of the government’s and Cross’s evidence. Moreover, the district court’s deferral of its ruling did not adversely affect Cross’s ability to raise this issue on appeal.
See
Fed.R.Crim.P. 12(e) (determination of pre-trial motions may be postponed until trial "for good cause");
United States v. Beard,
. Because it challenged the truth of the indictment’s allegations, the district judge properly determined that the immunity issue presented a factual question for the jury, and that it was therefore not within the province of the court ultimately to weigh the government’s and Cross’s evidence on this matter.
See United States v. Ayarza-Garcia,
. We find Cross’s generalized claim of error based on the purported immunity agreement to be without merit regardless of whether we examine the trial court’s evidentiary ruling under a clearly erroneous standard of review,
see United States v. Weiss,
. Cross places false weight on a 1981 draft letter sent to Cramer by Brick. The letter, which was originally drafted by Cramer and modified by Brick, was to be sent to Florida parole officials on Cross’s behalf. It erroneously stated that an immunity agreement had been “issued" for Cross’s "future association with the porno-trade during the course of his assistance" to the Department. Cramer testified that he knew that Brick's failure to change or remove this phrase from the draft letter did not mean the immunity agreement had been signed or approved. The proof at trial clearly showed that Cross had no reason to, and in fact did not, infer from this stray, incorrect comment that he henceforth had license to establish a pornographic enterprise.
. The "Contract of Immunity” indicated that if he cooperated with law enforcement officials, Cross would not be prosecuted for past pornographic activities or for future attempts to solicit child pornography. As such, it did not cover Cross’s mailings of pornographic photos or attempts to have these photos prepared for commercial distribution.
. The agreement contained labeled blank spaces for the signatures of the state attorney and an assistant state attorney, but was never signed by either of these officials. Although prison investigators discovered in Cross's cell a copy of the immunity agreement which purportedly was signed by an assistant state attorney named "Richards,” the government presented evidence that no lawyer by this name worked in the office of the state attorney. There was also testimony from one of Cross’s then-fellow prison inmates that Cross had tampered with the document, as well as testimony from a handwriting expert that the "Richards" signature was similar to Cross’s and that Cross had disguised his handwriting exemplars. Cross's duplicity in this matter clearly indicates he was aware that he had no valid immunity agreement with law enforcement officials.
. In 1981, Syring informed Cross that he was being transferred to Fort Myers, Florida, and instructed Cross to contact him when he was granted immunity. Syring never again heard from Cross.
. Although Cramer did provide the Department with copies of several of Woodward’s California photographs, these were different photos than the ones sent to Lodge. Moreover, as with the Tampa photos, no government official was informed of or approved Cross's mailing of the California photos to Lodge, although Cross had given Lodge’s and Woodward’s names to several law enforcement agents.
. We must note, however, that the court is disturbed by the somewhat careless and slipshod fashion in which government agents dealt with Cross, who even then was a notorious confidence artist.
. The government presented evidence that Cross's ulterior motive in pretending to act as an informant was not only to avoid criminal punishment if the Tampa hoax were detected, but also to further the scheme itself: A then-fellow prison inmate testified that Cross had told him that he was attempting to parlay his cooperation with a Senate subcommittee investigating child pornography into a parole in the New York area, where Cross hoped to establish a phony office in order to take additional nude pictures of the Tampa girls and sexually molest several of them.
. Rule 404(b) provides:
Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show action in conformity therewith. It may, however, be admissible to for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.
. Such evidence is relevant if “offered for ... a proper purpose," and if “the jury can reasonably conclude the act occurred and that the defendant was the actor.”
Huddleston,
. The indictment alleges that the conspiracy stretched from October 1980 to May 1983. Cross’s correspondence with Lodge dated back only as far as 1975.
. Proof of such intent was essential to the government’s case against appellants on both the conspiracy and mail fraud counts. Lodge’s defense at trial challenged the government’s case on this issue by suggesting that Lodge was a passive recipient of the Tampa photos from Cross and that he never planned to process or market these pictures. Similarly, Cross suggested that he obtained the Tampa photos with the legitimate intent of casting an actual documentary film.
. Rule 403 provides:
Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.
Unfair prejudice "means an undue tendency to suggest decision on an improper basis, commonly, though not necessarily, an emotional one.” Notes of Advisory Committee on Proposed Rule 403.
.
See also United States v. King,
. Of course, the post-1980 letters were even more crucial to the government’s case, as they were offered to prove the existence of, and each appellant’s membership in, the conspiracy itself.
. Although Cross contends that he suggested only a one- or two-day postponement, his request was more of an open-ended one, as he asked to call his daughter as a witness "during the next two dates, possibly, whenever she is available to come.”
. Cross has not challenged on appeal Lanning’s qualifications as an expert on pedophilia. At the time of trial, Lanning was a supervisory special agent assigned to the behavioral science unit at the FBI Academy. He had specialized for some time in training, research, and consultation involving the criminal victimization of children.
.
See Mishkin v. New York,
. Lanning also indicated that, in communicating with one another, pedophiles often employ the term, “nude studies” — a phrase repeated in Cross’s letters — as a “code word," to refer to such non-obscene photographs of children.
See United States v. Alfonso,
. In quoting, from
United States v. Gillespie,
. The decision in
Anderson,
involving a defendant charged with transporting minors for prostitution, is particularly applicable to this case. There too, expert testimony was presented to rebut the defendant’s claim that his conduct was innocent rather than criminal. The court held that expert testimony regarding "pimping patterns and the pimp-prostitute relationship,” was properly admitted to assist the jury in evaluating the defendant’s contention that he was “merely a gambler with a flashy lifestyle and a penchant for travel.”
Id.,
. See section V(B) of the court’s opinion.
. Cross also complains that the district court failed to caution the jury against considering Lanning's testimony as evidence of Cross’s bad character or disposition to commit the crimes charged. However, neither Cross nor Lodge ever requested such a limiting instruction, and the failure of the court to provide one,
sua sponte,
was not plain error.
See Burchfield,
Similarly, Cross failed to object at trial to Lanning’s comment that the FBI would not allow an informant to molest children or otherwise violate the law, although he now claims on appeal that the admission of such testimony was reversible error. Read in context, Lanning mentioned "molestation" only as an example of criminal conduct, and never alleged or implied that Cross was accused of physically abusing children. Such a brief, non-suggestive reference was itself hardly damaging to Cross, and the trial court’s failure to order the jury to disregard it was not plain error.
. Rule 801(d)(2)(E) provides that "a statement by a coconspirator of a party during the course and in furtherance of the conspiracy” is not considered hearsay.
. Cross also contends that the district court should have determined the admissibility of these statements by conducting a hearing prior to permitting the government to introduce them into evidence.
See United States v. James,
. Although Cross does not object to other statements by Diwan, introduced by the government in the form of hearsay through the testimony of parents of the Tampa models, we note that such evidence, in contrast, was properly admitted. Diwan communicated with the parents while masquerading as an assistant to Cross’s film project and for the purpose of obtaining nude photographs of the models. The government provided ample evidence of her participation in the conspiracy, and also proved that she made these statements to the parents in furtherance of the conspiracy.
. “Factors to consider” in determining whether the error was "harmless beyond a reasonable doubt" include "the importance of the evidence to the prosecution, whether the evidence was cumulative, and the overall strength of the prosecution’s case."
Turner,
. Cross cites a purported August 1987 letter by Mumpower, sent to Diwan’s attorney and the district judge, in which he threatens to "consider full recantation of all testimony given in the cause of U.S. v. Eric Cross,” unless government officials improve the conditions of his confinement. Cross has also submitted with his reply brief a copy of an affidavit by another inmate, who claims Mumpower admitted to perjuring himself at Cross’s trial.
. Rule 33 provides that a motion for a new trial based on newly discovered evidence must be made no later than two years after final judgment. Cross was sentenced on May 16, 1986 and, therefore, would have had to file his motion no later than May 16, 1988. Although Cross’s appeal was pending during this period, he was free to move this court to remand his case back to the district court to enable him to file his new trial motion.
See
Fed.R.Crim.P. 33;
United States v. Khoury,
. Neither of the documents on which Cross relies — the letter from Mumpower and the other prisoner's affidavit — are part of the record on appeal.
. Cross filed a pre-trial motion to dismiss the indictment on these grounds.
. The district court heard oral argument from Cross and the government on this issue. Although the court denied Cross's request that an evidentiary hearing be held to allow his standby counsel to testify that the witness list was sealed when it was filed, we have, in deciding this claim, accepted Cross’s allegation that the witness list was filed in a sealed condition.
. Before she fled the country, Diwan testified regarding her concerns that her attorney was colluding with the prosecution at a hearing on her request to be appointed new counsel.
. Cross complains that the district court failed to order that cassette tapes contained in Diwan’s bank safety deposit box be turned over to the court. He claimed that the tapes were a recording of the conversation in which Diwan’s attorney told her to consider absconding. Cross furnished the district court with a transcript of the alleged conversation, which the court refused to consider on grounds of lack of authentication and Diwan’s attorney-client privilege, but which was made part of the record for appellate review. Because we have taken into account the contents of the transcript in determining that there was no proof of government misconduct, we need not address Cross’s argument that the district court erred in failing to subpoena the tapes.
