Our principal concern in considering the defendant’s appeal is whether the circumstances of the crime for which he was charged were so likely to release the venom of racial prejudice that the trial judge ought to have examined prospective jurors individually about racial bias, as requested by defense counsel. See G. L. c. 234, § 28; Mass.R.Crim.P.
Jose Ramos, Jr., was convicted by a jury of assault and battery by means of a dangerous weapon and acquitted of a charge of assault with intent to murder. The crime was an unprovoked stabbing of Andrew Lubatty, who was simply walking home on a public street (Dartmouth Street in Boston) with three friends after sharing dinner at a local restaurant on a Saturday evening. Before the stabbing occurred, Ramos had “bumped” Lubatty and asked him repeatedly, “What are you doing?” To that Lubatty had replied, “Nothing; everything is fine,” and had sought to disengage.
Now anxious, Lubatty and his friends, another man and two women, continued on their way. Very shortly thereafter, they realized a “group of people” or a “number of people,” variously described as six to fifteen, were running towards them. At the head of the pack was a man in a fur coat, the same man involved in the “bumping” incident, who cried, “Get him.” The foursome tried to flee, but Ramos caught Lubatty between parked cars, stabbed him twice in the back with a knife, and was winding up for a third thrust when one of the women managed to pull Lubatty away and the four found sanctuary in another restaurant, Claddagh’s. Lubatty and his friends are white; the defendant and a youth — he was tried as a juvenile — who participated actively in the knifing of Lubatty were described varyingly as dark-skinned and light-skinned Hispanics.
1.
Individual examination of prospective jurors.
In the generality of cases, it is for the judge to decide whether the case to be tried is likely to generate extraneous influences alluded to in G. L. c. 234, § 28, such as racial bias.
Commonwealth
v.
Shelley,
Beginning with the
Sanders
case, the court began to establish a select category of cases in which racial bias infection of the jury venire was so distinct a possibility that the judge would be compelled to examine jurors individually to see if the capacity of any to render a disinterested verdict had been affected. So, in
Sanders,
interracial rape was stated to be a crime so likely to trigger racial bias that a judge ought to conduct individual voir dires of potential jurors.
Commonwealth
v.
Hobbs,
385 Mass, at 873, extended the requirement to interracial assault and sexual abuse of a child. In
Commonwealth
v.
Young,
The difficulty for the defendant is that the record does not support such a view of the case. Of the racial composition of the defendant’s group we know scarcely anything. It is likely that the group was Hispanic, but we cannot assume it, and Hispanic, as such, would not constitute a racial category for purposes of applying § 28 and the
Sanders
rule.
Commonwealth
v.
De La
Cruz, 405 Mass, at 272-274. As presented, the prosecution’s case did not refer to a gang attack. Indeed, the word “gang” never came into play. There was reference to a “group” of young men who pursued the four whites with the assailants at their head; there was no direct reference by the prosecutor to the race or racial characteristics of the defendant. The jury, of course, could see the defendant. In the record, witnesses describe the defendant as: “Hispanic male 5’8”; “one is 5’8 with a multi-colored fur coat and a Yankee baseball cap on”; “a light skinned black male about 5’8 with a slight mustache, wearing a coat”; “5’8, light skinned black or Hispanic male”; “a light-skinned Hispanic male”; “light-skinned black or Hispanic male, slight build, mustache, short hair and late teens”; “the three kids looked Hispanic”. The race of the defendant was, it seems, uncertain. Neither the testimony of witnesses nor — and we think this particularly important — the opening statement and closing argument of the prosecutor spoke of a gang attack or alluded to racial differences between the assailant and the victim. Compare
Taken all in all, the trial was racially neutral and we think the seepage of racial prejudice into the jury was unlikely. Of course, when the motion for an individual voir dire was made, the Superior Court judge had no way of knowing how the trial would play out. She would surely have been wiser to conduct the individual voir dire when asked so to do, but, with the luxury of the completed record before us, we are not prepared to characterize her refusal as reversible error. This is particularly so because all previous extensions of the Sanders rule have been prospectively applied.
2.
Specific unanimity instruction.
After the judge’s charge to the jury, but before the jury retired to deliberate, defense counsel requested what has acquired the label of a “specific unanimity instruction,” i.e., an instruction to the jury that if there are alternative sets of facts or episodes which support a finding of guilty, the jury must reach a unanimous verdict as to at least one of those specific sets of facts or episodes. See
Commonwealth
v.
Comtois,
“a unanimity instruction is required only if the jurors could otherwise disagree which act a defendant committed and yet convict him of the crime charged .... The possibility of disagreement exists where the defendant is accused of a number of unrelated incidents, such as alleged rapes at different times or places, leaving the jurors free to believe different parts of the testimony and yet convict the defendant.”
For purposes of decision, we can assume the defense adequately called to the trial judge’s attention, conformably with Mass.R.Crim.P. 24(b),
Unlike those cases in which evidence of separate occurrences came before the jury, and a specific unanimity instruction was, therefore, indicated, in this case there was evidence of but one event. In the context of that event the jury had alternative theories upon which to find the defendant guilty: he stabbed Lubatty while his accomplice with the baseball cap held Lubatty down, or, the defendant held the victim down while the accomplice stabbed him. If the former were the scenario, the defendant would be guilty as a principal; if the latter, he would be guilty as a joint venturer.
Inherent in the idea of joint venture culpability is that the joint venturer, as an aiding and abetting party, shares the same mental staté, and is as guilty as the principal who commits the crime.
Commonwealth
v.
Soares,
3.
Instruction on credibility of witnesses.
Prior to the charge conference, the defense filed a motion requesting the judge to refrain from instructing the jury that, in assessing the credibility of a witness, they could consider the interest of the witness in the outcome of the case. The judge did not honor the request, and the point was preserved by defense counsel with a timely objection and request for correction at the close of the charge. There was no error. It is appropriate for a judge to mention that interest in the case is a criterion, along with others which the judge detailed, for assessing the credibility of witnesses. See
Commonwealth
v.
Perez,
Judgment affirmed.
Notes
Requiring individual voir dire in certain cases to implement the statutory purpose of G. L. c. 234, § 28, has been an exercise of the Supreme Judicial Court’s power of “general superintendence of all courts of inferior jurisdiction to correct and prevent errors,” G. L. c. 211, § 3, as amended through St. 1973, c. 1114, § 44, rather than the consequence of any constitutional requirement. Commonwealth v. Young, 401 Mass, at 398. Commonwealth v. De La Cruz, 405 Mass, at 272. Commonwealth v. Grice, 410 Mass, at 589 n. 5. We think it our duty, as we did in Stephens, to consider circumstances in which the Sanders rule might apply, i.e., to fill the interstices of opinions of the Supreme Judicial Court on the subject.
Defense Counsel: “I would also ask that you instruct the jury that when they reach a verdict, given that the Court, over my objection, had laid out several different theories of guilt, that they must agree on the theory and they must agree on the facts. They must find the facts unanimously and not find the defendant guilty under different theories.”
The Court: “I don’t understand what you mean by that.”
Defense Counsel: “For example, if half the jury thinks he was the principal and half the jury thinks he was a co-venturer, that they may not then find the defendant guilty with inconsistent findings of fact.”
