The defendant, Carl H. Drew, was convicted of murder in the first degree and sentenced to a term of life imprisonment at the Massachusetts Correctional Institution, Cedar Junction. The defendant’s motion for a new trial was denied. 1 On appeal, the defendant contends that the trial judge erred in (1) refusing to issue a writ of habeas corpus ad tes *67 tificandum to procure the attendance of a witness necessary to his defense; (2) allowing the introduction of evidence regarding the defendant’s alleged participation in Satanic cult rituals; (3) allowing the introduction of evidence of other crimes allegedly committed by the defendant; (4) denying the defendant’s motion to sit at counsel table during trial; and (5) instructing the jury. The defendant also requests that we exercise our power under G. L. c. 278, § 33E. We affirm the conviction. We conclude there is no reason to exercise our power under G. L. c. 278, § 33E, in favor of the defendant.
We first sketch the facts as they may have appeared to the jury, later adding additional detail as needed for analysis. On April 13, 1980, a portion of a human skull was found in the woods near an area known as “Family Beach” in Westport, Massachusetts. A subsequent search of the area yielded various items of clothing, bloodstained rocks, jewelry, and a clump of hair. The remains were identified as those of the victim, Karen Marsden, a young woman from Fall River.
From February to November, 1979, Marsden had worked for the defendant as a prostitute in the Bedford Street area of Fall River. In the summer of 1979, Marsden met Robin Murphy, who was also acquainted with the defendant. There was evidence that Marsden and Murphy, along with other prostitutes and pimps from the Fall River area, attended Satanic ritual meetings conducted by the defendant. On the evening of October 12, 1979, while in the presence of Marsden, Murphy, and another, the defendant killed another prostitute, Doreen Levesque. According to Murphy’s testimony, 2 the killing was performed as a diabolic ritual during which the soul of Marsden was purportedly given to Satan.
Following the death of Levesque, the relationship between Marsden and the defendant deteriorated. Marsden attempted to sever her relationship with the defendant and with the Satanic *68 cult. Marsden and the defendant frequently argued and the defendant threatened to kill her on several occasions. In December, 1979, Marsden went into hiding from the defendant. She began living with Murphy and another woman, Carol Fletcher. Also at this time, Marsden met five or six times with an officer of the Massachusetts State police who was investigating the death of Levesque. During December, 1979, and January, 1980, the defendant made repeated inquiries as to Marsden’s whereabouts. On February 4, 1980, he told Fletcher that “in the right time and the right place he was going to kill Karen.”
On the evening of February 8, 1980, Marsden, Fletcher, and Murphy were riding in Fletcher’s automobile along Bedford Street. At some point, the defendant got into the car, along with one Carl Davis. Davis directed Fletcher to drive to Family Beach in Westport. When the group arrived there, the defendant ordered Murphy to take Marsden out of the car. Murphy dragged Marsden by the throat and hair into the woods. As she did this, the defendant walked alongside while Fletcher and Davis followed close behind. Murphy and the defendant then began striking Marsden with rocks. After further brutalizing Marsden, the defendant ordered Murphy to slit Marsden’s throat and Murphy complied. The defendant then tore the head from the body and kicked it. Some months later, the defendant admitted to Lea Johnson, who was then working for and living with the defendant, that he had killed “a girl” in the presence of Murphy, Davis, and another woman. He recounted in detail how she had been killed, and told Johnson that he had killed the girl “because she wanted to leave the cult” and that “he wanted her to feel pain.”
The defendant presented a defense of alibi. He testified that he had spent the evening of the murder in two bars on Bedford Street. Margarida Revorido testified that she worked for the defendant that evening as a prostitute and that she was never out of the defendant’s presence for longer than fifteen or twenty minutes. On cross-examination, Revorido admitted that she was always with the defendant on Friday evenings, and that she had no way of distinguishing Friday, February 8, from any other Friday.
*69 1. The denial of the request for a writ of habeas corpus ad testificandum. The defendant asserts that the judge erroneously denied his request for a writ of habeas corpus ad testificandum to procure the attendance of an inmate-witness. The defendant contends that this denial precluded his Sixth Amendment rights to present a defense. 3
The defendant called Carl Davis as a witness. At a voir dire hearing, Davis invoked his Fifth Amendment privilege against self-incrimination and refused to testify. The defendant then requested that a writ of habeas corpus ad testificandum be issued for one Raymond Bertrand. The judge denied the request. The defendant’s counsel, on the record, made an offer of proof in which he indicated that had the writ of habeas corpus been issued, Bertrand would have testified to the following facts. Following their indictments for the murder of Karen Marsden, the defendant and Carl Davis were incarcerated together in the Bristol County house of correction awaiting trial. On August 29, 1980, while in the presence of the defendant and Bertrand, Davis allegedly wrote out a statement in which he admitted “being present at the scene of the homicide and doing certain acts concerning it.” Davis allegedly described who was present and specifically excluded the defendant, writing, “I don’t know why Carl Drew’s name was mentioned, he wasn’t there.” After writing this statement, Davis purportedly showed it to the defendant and to Bertrand, but then destroyed it, and refused to write another copy. At the defendant’s request, Bertrand wrote down his recollection of Davis’s statement.
Rule 17 (b) of the Massachusetts Rules of Criminal Procedure,
In his offer of proof, the defendant contended that Bertrand’s testimony should be admitted under the exception to the hearsay rule for statements of a coconspirator.
4
The judge correctly rejected that argument. In this Commonwealth, “[i]t is well settled that, to be admissible against a defendant, the out-of-court statements of coconspirators or joint criminal venturers must have been made during the pendency of the criminal enterprise and in furtherance of it. See, e.g.,
Commonwealth
v.
White,
Nor does the exclusion of Bertrand’s testimony violate the defendant’s Federal constitutional right of due process.
5
The United States Supreme Court has held that “the hearsay rule may not be applied mechanistically to defeat the ends of justice.”
Chambers
v.
Mississippi,
Similarly, in
Green
v.
Georgia,
“The record before us is barren of any showing that the excluded evidence was circumstantially trustworthy or bore ‘considerable assurance of . . . reliability. ’
Chambers
v.
Mississippi, supra
at 300.”
Commonwealth
v.
Wilborne,
*73
On appeal, the defendant argues that Bertrand’s testimony was necessary to his defense and that the testimony would have been admissible under the exception to the hearsay rule for admissions against penal interest. See
Commonwealth
v.
Carr,
In
Commonwealth
v.
Carr, supra,
we adopted in substance principles expressed in Rule 804(b)(3) of the Federal Rules of Evidence (1985),
7
governing the admissibility of statements against interest.
Id.
at 623. A statement is admissible under rule 804(b)(3) if it meets three tests: “[1] [T]he declarant’s testimony must be unavailable; [2] the statement must so far tend to subject the declarant to criminal liability ‘that a reasonable man in his position would not have made the statement unless he believed it to be true’; and [3] the statement, if offered to exculpate the accused, must be corroborated by circumstances clearly indicating its trustworthiness.”
United States
v.
Thomas,
The statement here meets the first test. The declarant’s testimony was unavailable because Davis invoked his Fifth Amendment right not to incriminate himself.
Commonwealth
v.
Hesketh,
We do recognize, however, that “the language of [Fed. R. Evid.] 804(b)(3) is not so narrow as to preclude all declarations but direct admission of guilt.”
Commonwealth
v.
Keizer,
*75
Nevertheless, Davis’s statement is not admissible because there are no “corroborating circumstances [that] clearly indicate the trustworthiness of the statement.” Fed. R. Evid. 804(b)(3). In
Carr, supra
at 624, we stated: “In applying the corroboration requirement, judges are obliged to exercise a discriminating judgment .... [The judge] will consider as relevant factors the degree of disinterestedness of the witnesses giving corroborating testimony as well as the plausibility of that testimony in the light of the rest of the proof.” See
Commonwealth
v.
Doherty,
The judge should assess “both the credibility of the declarant and the credibility and the probativity of his statement.” Tague, Perils of the Rulemaking Process,
In deciding whether to admit a statement against penal interest, the judge should not base his determination on an assessment of the proffered witness’s credibility. The jury, rather than the judge, should evaluate the credibility of the witness. The government can cross-examine the witness, which enables the jury to evaluate the witness’s demeanor and credibility.
11
Additionally, a decision by a trial judge to exclude the testimony of a witness solely because the defendant has not established the credibility of the witness may be violative of the defendant’s constitutional rights under the compulsory process
*77
and due process clauses.
United States
v.
Satterfield,
In this case, even if the defendant had called the judge’s attention to
Commonwealth
v.
Carr,
the judge would have been correct in excluding Davis ’ s statement. The judge properly could have found Davis’s statement not trustworthy. Only the defendant’s testimony corroborated the critical portion of Davis’s statement: that the defendant was not at the scene.
12
The lack of detail about the crime, and the lack of factual details as to the involvement of the declarant in the crime also detract from the credibility of the statement. Nor do the circumstances in which the alleged statement were made support its trustworthiness. The statement was made by a codefendant, while incarcerated with the defendant, several months after their indictments. The statement was neither spontaneous nor contemporaneous with the defendant’s or the declarant’s arrest or incarceration. Compare
United States
v.
Thomas, supra
(statement made spontaneously in front of a number, of people, including United States magistrate), with
United States
v.
Zirpolo,
We conclude that the offered statement was not “clearly corroborated” and was therefore not admissible. Neither rule 804(b)(3) nor the
Chambers
case requires judges indiscriminately to admit evidence which “because of the lack of opportunity for cross-examination and the absence of the declarant, is open to easy fabrication.”
United States
v.
Barrett,
2. Evidence of Satanic cult rituals. The defendant contends that the judge erred in admitting over objection evidence regarding the defendant’s participation in Satanic cult rituals. Several witnesses testified to the defendant’s cult practices, and the defendant was asked to remove his jacket to exhibit a tattoo ón his arm of a devil’s head with the partially obliterated inscription “Satan’s Avengers.” The defendant argues that this evidence was not relevant or, in the alternative, that any probative value it may have had is substantially out weighed by its prejudicial impact on the jury. See Proposed Mass. R. Evid. 403.
The Commonwealth’s evidence indicated that the defendant conducted Satanic rituals that were attended by the victim, Robin Murphy, and others. At the rituals, the defendant chanted in a “low, scratchy voice,” purportedly to conjure Satan’s presence. There was also evidence showing that the killing of Doreen Levesque was performed as a ritual during which the soul of the victim (Marsden) purportedly was given to Satan, and that after that killing the victim attempted to sever her *79 relationship with the defendant and with the Satanic cult. Other evidence showed that the defendant admitted murdering the victim because she wanted to leave the cult. Finally, there was evidence that immediately following the murder of the victim, the defendant and Murphy knelt beside the body while the defendant cut an “X” on the victim’s chest and spoke in the same “low, scratchy voice” that he used when he conducted the Satanic rituals. The defendant then put some of the victim’s blood on Murphy’s forehead and stated to her “now you are one of us.”
The prosecutor was entitled to present as full a picture as possible of the events surrounding the incident itself.
Commonwealth
v.
Chalifoux, 362
Mass. 811, 816 (1973). The evidence here showed the “entire relationship” between the victim and the defendant.
Commonwealth
v.
Young,
3.
Evidence of other crimes.
The defendant next challenges the introduction of evidence over objection of the defendant’s alleged murder of Doreen Levesque. The defendant argues that this evidence was not relevant to the crime for which he was on trial, and that it was highly prejudicial. “[T]he prosecution may not introduce evidence that a defendant previously has misbehaved, indictably or not, for the purpose of showing his bad character or propensity to commit the crime charged,”
Commonwealth
v.
Trapp,
There was evidence that the defendant murdered the victim because she was an eyewitness to the Levesque murder and in retaliation for her speaking to the police. There was also
*80
evidence that, shortly after the Levesque murder, the victim attempted to sever her ties to the defendant, that he threatened to kill her, that she hid from the defendant, and that the defendant knew she was hiding from him and knew she was talking to the police. He said that “he want[ed] Karen back because she knew too much. ” The evidence was relevant to show motive and therefore admissible.
Commonwealth
v.
Weichell,
4. Denial of the defendant’s motion to sit at counsel table during trial. The defendant maintains that the judge erred in denying his pretrial motion to be seated at counsel table. The defendant argues that this error was prejudicial because trial counsel was without an assistant and had not had an opportunity to interview all the witnesses, and because no curative instructions were given on the seating of the defendant.
The Commonwealth opposed the defendant’s pretrial motion on the grounds that implements of escape had been found in an inmate’s cell at the Bristol County house of correction and that confidential informants still within the jail had told the Commonwealth that the implements were part of a planned escape attempt involving the defendant and two other inmates. The defendant renewed his motion at the start of trial. On the basis of the Commonwealth’s information, the judge concluded that the defendant was a security risk and therefore denied the motion. 14 The defendant was seated in a chair at the rear of *81 the bar railing, approximately twelve feet from defense counsel table. A uniformed court officer sat next to the defendant.
“Ordinarily, a criminal defendant should be permitted to sit at counsel table.”
Commonwealth
v.
Moore,
The judge specifically found that seating the defendant at counsel table would be a risk to security and so stated on the record. The judge’s reliance in part on hearsay is of little consequence because ordinary rules of admissibility do not apply to such situations.
Commonwealth
v.
Brown, supra
at 479. There is no indication that the defendant and his counsel had any difficulty conferring with each other or that separate seating diminished the effectiveness of defense counsel.
Id.
at 477.
Commonwealth
v.
Campbell,
5.
Charge to the jury.
The defendant challenges the judge;’s charge to the jury on several grounds. The defendant did not raise these objections at the conclusion of the charge. We therefore review the challenged instructions to determine whether the charge as given created a “substantial risk of a miscarriage of justice.”
Commonwealth
v.
Anderson,
a. The defendant argues that the judge’s instructions to the jury on how to evaluate the credibility of witnesses trivialized the responsibility of the jurors by equating their decisions with those encountered in their daily lives. See
Commonwealth
v.
Garcia,
The defendant’s reliance on
Garcia
and
Ferreira
is misplaced. In those cases, we held that the use of specific examples of decisions from the jurors’s business and personal lives to illustrate the burden of proof beyond a reasonable doubt may so trivialize the awesome duty of the jury as to be constitutional error.
Commonwealth
v.
Garcia, supra
at 439-440.
Commonwealth
v.
Ferreira, supra
at 129. The challenged portion of the charge related not to reasonable doubt but to assessment of witness credibility. See
Commonwealth
v.
Little,
b. The defendant next objects to the instruction on the use of inferences, in which the judge used an example that the defendant alleges parallels the facts of the case. The example referred to stolen jewelry. The defendant argues that this example was prejudicial because jewelry found near the victim’s remains was a factor in identifying the victim.
The judge’s reference to stolen jewelry was made in the context of a discussion of inferences. It was preceded by another example of drawing inferences from footprints discovered after a recent snowfall. We do not believe that a reasonable juror would have confused the judge’s example as an expression of belief in the Commonwealth’s proof concerning the identity of the body. Compare
Commonwealth
v.
Gil,
c. The defendant also challenges the judge’s instructions regarding the use of prior convictions to impeach. The defendant focuses on the judge’s statement, “You may decide that you don’t care, it doesn’t bother you that somebody may have an automobile violation or something of that nature or other offenses, whatever may be charged. But that is known as impeaching credibility. Whoever presents it is saying to you: do you believe this person? They have been convicted of this, this and this. But only insofar as it affects your belief of them will you use it.” The defendant argues that the reference to an automobile violation, when contrasted with the three armed robbery convictions with which the defendant was impeached “unfairly pushed the jury towards an almost automatic use of the armed robbery convictions to impeach the defendant’s credibility.”
This argument has no merit. The judge’s full instructions on use of prior convictions for impeachment directed the jury to determine whether any prior convictions introduced for impeachment purposes involved moral turpitude, and, if so, whether that would affect the jurors’ judgment of a witness’s credibility. Viewed in the context of the entire charge, the instructions were sufficient to inform the jury that “they are the ultimate arbiters of credibility, and that it is for them to decide whether, and to what extent, a crime may affect credibility.”
Commonwealth
v.
Bumpus,
*84 6. G. L. c. 278, § 33E. We have examined the entire case on the law and the evidence and conclude that there is no reason to order a new trial or direct the entry of a verdict of a lesser degree of guilt.
Judgment affirmed.
Notes
Prior to the entry of the defendant’s appeal in this court, the defendant filed a motion for new trial in the Superior Court. That motion was filed pursuant to Mass. R. Crim. P. 30,
Murphy was indicted for the murder of Karen Marsden and pleaded guilty to murder in the second degree. In exchange for testifying truthfully, she was granted immunity from further prosecution in the matter and for her involvement in the death of Doreen Levesque.
The defendant relies solely on a claim of violation of his Federal constitutional rights.
At trial and at the hearing on the motion for a new trial, the defendant relied on
Dutton
v.
Evans,
We treat the defendant’s citation at trial to Dutton v. Evans, supra, and Bruton v. United States, supra, see note 4, supra, as sufficient to raise the issue whether the exclusion of Bertrand’s testimony violated the defendant’s due process rights.
Generally Chambers-based claims have been consistently rejected by the courts.
Commonwealth
v.
Carr,
Rule 804(b)(3) provides: “(b) Hearsay exceptions. The following are not excluded by the hearsay rule if the declarant is unavailable as a witness: ... (3) Statement against interest. A statement which was at the time of its making so far contrary to the declarant’s pecuniary or proprietary interest, or so far tended to subject him to civil or criminal liability, or to render invalid a claim by him against another, that a reasonable man in his position would not have made the statement unless he believed it to be true. A statement tending to expose the declarant to criminal liability and offered to exculpate the accused is not admissible unless corroborating circumstances clearly indicate the trustworthiness of the statement.”
We note that behind the corroboration requirement of rule 804(b)(3) lurks a suspicion that a reasonable man might sometimes admit to a crime he did not commit. A classic example is an inmate, serving time for multiple offenses, who has nothing to lose by a further conviction, but who can help out a friend by admitting to the friend’s crime. See, e.g.,
United States
v.
Silverstein,
These ambiguities have been the subject of judicial and scholarly criticism. See, e.g.,
Commonwealth
v.
Doherty, supra
at 354 (Liacos, J., concurring);
United States
v.
Silverstein,
In determining whether the declarant’s statement has been sufficiently corroborated to merit its admission in evidence, the judge should not be stringent. A requirement that the defendant corroborate the declarant’s entire statement, for example, may run afoul of the defendant’s due process rights under
Chambers
v.
Mississippi.
See
United States
v.
Barrett,
We observe that the Federal Circuit Courts of Appeal are divided on the question whether a judge may consider the credibility of the witness as well as the credibility of the declarant. Compare
United States
v.
Bagley, supra
(trustworthiness of witness relevant) with
United States
v.
Atkins,
Rarely will the defendant’s testimony alone be considered sufficient corroboration for the hearsay statement. See
United States
v.
Tovar,
The defendant assumes, without discussion, that violation of rule 804(b)(3) automatically is constitutional error. “[T]he federal rule is no more restrictive than the Constitution permits, and may in some situations be more inclusive.” United States v. Barrett, supra. See Commonwealth v. Carr, supra at 625. Ordinarily, an error in the admission or exclusion of evidence is not of constitutional import.
At the hearing on the motion for a new trial, the judge explained that his conclusion that the defendant was a security risk was also based in part on the judge’s awareness that the defendant was about to be indicted on another murder charge.
The judge did not specifically caution the jury against drawing any inferences from the defendant’s separate seating. No such instruction appears to have been requested. The record does not disclose any reason for concluding that failure to give such an instruction creates a substantial risk of a miscarriage of justice.
