Hennessey, C.j., Braucher, Wilkins, Liacos, & Abrams, JJ.
Homicide. Practice, Criminal, Sequestration of witnesses, Capital case.
The opinion of the court was delivered by: Braucher
At a murder trial, the Judge's refusal of the defendant's motion to sequester witnesses did not prejudice the defendant. [850-851]
At a murder trial, evidence that the defendant, after a quarrel with the victim in a hallway outside an apartment, went to the kitchen of the apartment, picked up a knife, and returned to the hallway to stab the victim warranted a finding of deliberate premeditation. [851-852]
Where there was no evidence at a murder trial from which the jury could reasonably have found that the victim was killed upon sudden combat or reasonable provocation, there was no error in the Judge's refusal to charge the jury on manslaughter. 
Where there was evidence from which a jury could find that a defendant acted with deliberate premeditation in killing the victim, this court declined to exercise its powers under G. L. c. 278, § 33E. [852-853]
The defendant appeals from a conviction of murder in the first degree. We hold that any error in the trial Judge's refusal to sequester witnesses was harmless beyond a reasonable doubt, that there was no error in the denial of a directed verdict as to murder in the first degree, and that the Judge was not required to charge the jury with respect to manslaughter. We also decline to disturb the result under G. L. c. 278, § 33E, and affirm the conviction.
The Commonwealth produced evidence of the following facts. Emma Sherrod lived in a first floor apartment in Boston, and had been "going with" the victim, a man who lived on the third floor. They "broke up," and she started seeing the defendant. On August 3, 1974, the victim had been drinking; he came to her apartment and "started hassling" her. Later he and the defendant had an argument outside the apartment or in the living room. The defendant ran into the kitchen, picked up a knife from the sink, and ran back into the hallway. The victim said, "Man, leave me alone." The defendant stabbed him, and he died. The defendant offered no evidence.
1. Sequestration of witnesses. Before the prosecutor's opening statement, the defendant moved to sequester the witnesses because the incident "happened nearly two years ago," and the witnesses were "known to each other, and friendly with each other." The Commonwealth did not oppose the motion. The Judge said he would adhere to his "usual practice" and deny the motion. "At least twice during the trial the question usually comes up," he said, "did they talk to someone outside, or did they sneak in the courtroom."
The three principal witnesses were Emma Sherrod and Cynthia Hart, who shared the first floor apartment, and the victim's male cousin. Sherrod testified to the events leading up to the argument and to seeing the victim lying in the hallway. The victim's cousin testified that he saw the stabbing and subsequent events from across the street. Hart testified that she was in the kitchen, heard the argument, saw the defendant run in and out of the kitchen, and heard the victim's statement before he was stabbed. Sherrod and Hart knew the defendant beforehand; only the victim's cousin gave a detailed description of the defendant.
The sequestration of witnesses lies within the sound discretion of a trial Judge, but the better practice in "capital cases" is to allow such a procedure. Commonwealth v. Vanderpool, 367 Mass. 743, 748-749 (1975), and cases cited. The defendant points out that in some jurisdictions the procedure is mandatory if requested by a party. See, e.g., Fed. R. Evid. 615; 6 J. Wigmore, Evidence § 1839 (Chadbourn rev. 1976). The advantages, he argues, outweigh the possibility of troublesome sequelae. See State v. Williams, 29 N.J. 27, 47 (1959). Adherence to a "usual practice" of denying such motions, he says, is not a proper exercise of discretion.
There is force in these contentions. But, assuming without deciding that an abuse of discretion was shown, we think it clear beyond a reasonable doubt that there was no resulting prejudice to the defendant. The three witnesses testified to different events, from different vantage points, and their accounts were not entirely consistent with each other. Two of them were identifying the defendant as a ...
