Lymаn appeals his conviction of conspiracy to transport in interstate commerce over $5,000 taken by fraud in violation of 18 U.S.C. § 371. 1 His appeal challenges the conduct of the prosecution and a key witness, Justheim; changes in and conformity at trial to the indictment against him; the naming of unindicted coconspirators; proof of a single conspiracy; and the failure of the court to give a requested instruction. We affirm.
During the trial, the government introduced evidence to the effect that Lyman and two government witnesses, Bradshaw and King, participated in a scheme involving their corporation (New Era) to defraud investors, among them Justheim and Watson, by false representations about the worth of ore from Llano, Texas (Llano ore), and the ability of their process (the New Era proсess) to extract precious metals from the ore. The scheme involved fraudulent tests of the ore for the investors at which the conspirators “salted” the ore to make it appear more valuable to the investors. Evidence also indicated that the conspirators made false representations about the existence of purchase orders for the ore.
Lyman contеnded that he believed that the New Era process could analyze precious metal content; that he did not know Bradshaw was salting the ore; and denied that he, Bradshaw and King had agreed to do so.
I
In his closing remarks to the jury, the prosecutor stated that Bradshaw was a good witness because he had kept notes in a diary “to refresh his recollection about dates and so forth.” Following the prosecutor’s argument, Lyman’s counsel moved for a mistrial and for discovery of the diary, stating that he had no knowledge of its existence. Later the same day, following the court’s instructions to the jury, Lyman’s counsel requested production of the diary on the basis of
Brady
v.
Maryland,
On appeal, Lyman asserts that if there is a diary, there should be a remand
*499
to the district court for a determination of whether it constituted material that should have been disclosed to the defense. There is, however, no court ruling for us to review. Counsel failed to pursue the question and obtain a decision. Therefore, we consider the matter to have been abandoned.
Cf. United States v. Mireles,
II
As a separate challenge pertaining to this incident, Lyman states that the diary remark to the jury was improper prosecutorial conduct. We must first decide whether Lyman’s objection to this remark was timely so as to have preserved the question for appeal. The government points out that Lyman’s counsel failed to object to the diary remark until the conclusion of the rebuttal argument. We see no reason, however, to require an interruption of the prosecutor’s argument. “[W]e recognize the tactical considerations that militate against interrupting an adversary’s closing argument.”
United States v. Trutenko,
The government concedes the remark about the diary was improper. In determining whether this requires reversal, we employ the test for nonconstitutional errors and look to whether it is more probable than not that the error materially affected the verdict.
United States v. Dixon,
Lyman makes a number of additional claims of prosecutorial misconduct, including a question asked of witness Watson as to whether the $100,000 he had loaned to Buchanan, a codefendant, was usеd for the purpose for which it was loaned. 4 A timely *500 objection was made. Watson answered that he did not check on what became of the money, and, therefore, as the trial court pointed out, all that was before the jury was Watson’s lack of knowledge. The trial judge immediately instructed the jury to disregard both the question and the answer. While the question should not have been asked, it probably did not materiаlly affect the verdict.
Lyman also accuses the prosecutor of misconduct due to his question of Lyman as to whether he recalled Bradshaw referring to his, Bradshaw’s, resume as “flowered” and whether he recalled hearing a Dr. Werner tell him he would go to Llano to draw some samples for New Era to test. These points were sufficiently preserved for appeal. Lyman contends there was nо evidence in the record to support these questions. Even if we assume there was error, we conclude it probably did not materially affect the verdict.
Lyman further asserts that the witness Justheim interjected various improper remarks to the jury during his testimony. At one point he referred to the alleged conspirators as “dirty crooks,” but the jury reported it had not heard the remark. Similarly, a juror to whom Justheim spоke while he was on the stand reported that she had not heard what he was saying. We cannot assume, as Lyman wishes us to, that other jurors heard him. There was no error pertaining to Justheim’s testimony.
Ill
Lyman next challenges the deletion of 20 of the 24 overt acts alleged in the indictment, and claims that the government’s evidence did not conform to the allegations in the indictment.
In Count I of the indictment, the grand jury charged a conspiracy and alleged at least 24 overt acts in furtherance of that conspiracy. In response to the government’s pretrial motion, the district court struck 20 of the overt acts and the indictment was retyped. Lyman characterizes the trial court’s action as an amendment to the indictment violating his Fifth Amendment right to indictment by a grand jury. We disagree.
While the court “may not by any means . . . alter the mаterial and essential nature of an indictment or broaden the offense charged,”
United States v. Dawson,
Nor was there a material variance between the indictment and the proof during trial of the conspiracy alleged in Count I. We have held that in order tо constitute grounds for reversal, a variance between
*501
proof and indictment must affect the substantial rights of the defendant by preventing him from presenting his defense properly, taking him unfairly by surprise, or exposing him to double jeopardy.
United States v. Bolzer,
Implicit in Lyman’s argument is the contention that a vаriance in proof may amount to a constructive amendment of the indictment. With this we may agree.
See Stirone v. United States,
We must also reject Lyman’s claim that the failure of proof of certain of the allegations at issue rendered the evidence of the agreement among the defendants insufficient. Again, we need not decide whether the allegations were proved, for none of these allegations was a material part of the indictment. It follows that their claimed absence cannot support a claim of insufficient evidence of the crime of conspiracy.
IV
Lyman moved before trial to dismiss the indictment against him because it named three unindicted cocоnspirators. Relying on
United States
v.
Briggs,
We have ordered the striking of the name of an unindicted party on grounds that the naming was beyond the authority of the grand jury and a denial of due process
*502
where “[ojther methods less injurious” to the party were available to satisfy the numerical requirement of the statute involved.
United States v. Chadwick,
There are some cases which discuss the lack of standing to object in similar situations.
See In re Jordan,
We need not decide, however, whether the trial court erred in denying the relief sought, for we conclude on this record thаt Lyman was not prejudiced. An indictment is not evidence,
Mason v. United States,
If, however, we construe Lyman to be asserting a violation of the due process rights of the unindicted third parties,
see United States v. Chadwick, supra,
In such a case, two distinct standing questions are presented. . . . First, whether [Lyman alleges] “injury in fact,” that is, a sufficiently concrete interest in the outcome of [his] suit to make it a case or controversy subject to a federal cоurt’s Art. Ill jurisdiction, and, second, whether, as a prudential matter, [Lyman is a proper proponent] of the particular legal rights on which [he bases his claim],
Singleton v. Wulff,
The Court has not provided the prudential guidelines necessary for our determination with specificity. The Court has generally considered the relationship between the litigant and the third party, e.
g., Craig v. Boren,
In analyzing these prudential qualifications, the plurality in
Singleton v. Wulff, supra,
divided with an equal number in the dissent as to what is required to meet the test. Under either description, however, we find Lyman’s position wanting. No argument is made, nor do we perceive one, which convinces us that the third parties could not assert their own rights. Nor is there any relationship between Lyman and the right holders to qualify him to assert their rights. Resolution of Lyman’s сhallenge to the naming of unindicted co-conspirators does not “ ‘dilute [] or adversely affect[]’ ” those parties’ rights.
See Craig v. Boren, supra,
V
Lyman further contends that various portions of the trial testimony established multiple conspiracies, rather than a single conspiracy. Specifically, he points to testimony that one Rindfuss sold tailings from a graphite mine to codefendant Lincecum in 1969; that Bradshaw met with two persons in Florida; that he met with O’Malley in Denver, from whom he obtained samples of graphitic material; that Bradshaw latеr wrote a letter stating that New Era had developed a “unique process to make concentrates salable”; that codefendant Wilson wanted to arrange to use the New Era process outside the United States; that Brungs purchased ore from O’Malley in Denver; that there was a New Era pilot project in Costa Rica; and that King traveled to Mexico to meet a man about a silver minе.
This evidence, however, does not raise the possibility of separate conspiracies. The Rindfuss testimony and Bradshaw’s trips were relevant to the manner in which Llano ore was obtained, as was the arrangement with Wilson. The letter was entered into evidence because Justheim, a victim of the conspiracy, had seen it. Nor was there testimony about the Costa Rica project or O’Malley sufficient to suggest a separate conspiracy. King’s interest in the silver mine merely established why he was in Mexico when one of the false representations about interest in Llano ore was made. We have held that the standard for determining the existence of a single conspiracy “ ‘is whether there was one overall agreement among the various parties to perform various functions in order to carry out the objectives of the conspiracy.’ ”
United States v. Kearney,
VI
Lyman requested an instruction which required the jury to find he had actual knowledge that Bradshaw was salting the test results in order to find him guilty. The underlying thеory of the instruction is that without such knowledge, Lyman could not have been a participant in the conspiracy. Lyman’s request is based on his argument that he believed in the New Era process and was unaware of the salting.
*504
The requested instruction was completely inadequate. There was other evidence pointing toward his guilt which the instruction failed to recognize. For example, there was testimony to the effect that Lyman participated in the decision to salt; that he participated in salting the ore; and that he had participated in the false representation of purchase orders. All of this testimony bore on Lyman’s knowing participation in the conspiracy. If such participation is established, it is not necessary that each conspirator be aware of all the details of the conspiracy.
See Chavez v. United States,
AFFIRMED.
Notes
. Lyman was convicted on the conspiracy count and acquitted on substantive counts based on 18 U.S.C. § 2314. Another defendant, Buchanan, was tried with Lyman and acquitted. Others named in the indictment as codefendants were Bradshaw, King, Lincecum, and Wilson.
. We are aware that in at least one circuit, it has been held that the failure to interrupt during closing argument is sufficient to foreclose review except under the plain error standard.
See United States v. Ward,
. Lyman also argues that' the prosecution’s “testimony” deprived him of his Sixth Amendment right to be confronted with the witnesses against him. This argument is unpersuasive.
. The prosecutor admitted he did not know the answer to the question but indicated that he had mistakenly thought he had some foundation for the question. We have stated that “our concern is with the prejudicial
effect
of the prosecutor’s error on the defendant and not, except in exceptional cases, with the inten
*500
tional or inadvertent nature of the error itself.”
United States v. Dixon,
. Defrauding of Brungs was irrelevant to the charge of conspiracy because completion of the substantive criminal objective is not an element of the crime of conspiracy.
United States v. Carman, 577
F.2d 556, 567 n.12 (9th Cir. 1978);
United States
v.
Root,
. One court has indicated that standing “in the strict legal sense” is not necessary to decide an application for expunction of a grand jury “presentment.”
