COMMONWEALTH vs. PETER J. CHONGARLIDES.

KANTROWITZ, J. The defendant provided heroin to Pamela Bouchard, who injected it and died as a result. He was charged with manslaughter, G. L. c. 265, § 13; distribution of heroin, G. L. c. 94C, § 32(a); and removal or conveyance of a human body, G. L. c. 272, § 71. A jury convicted him of all three charges. He appeals, claiming (1) the trial judge should have struck a prospective juror for cause because she knew the deceased; (2) the evidence was insufficient to sustain a finding

Page 710

of causation because, while the defendant only provided heroin, either the heroin or cocaine in her system could have caused death; and (3) the jury instructions were flawed in that they did not properly inform the jury that the heroin had to be "the" efficient cause of death "without which" the death would not have occurred. [Note 1] We affirm.

Facts. The facts are brief. On a January evening in Nantucket, the defendant met with, and supplied heroin to, the victim, Pamela Bouchard, and Thomas Dunham at the latter's home. Upon awakening from a drug-induced haze, Dunham saw the defendant on a bed and Bouchard on the floor, motionless. Thinking she had merely passed out, Dunham tried to revive Bouchard's lifeless body. Eventually, he realized she was dead. The defendant, who tried to help Dunham revive Bouchard, finally admitted to Dunham that "the greedy bitch kept wanting more, and she did eight bags and died." Instead of calling the police department, they stuffed her body under Dunham's bed. As they did, the defendant kicked her, exclaiming, "The dumb bitch died."

The following evening, after Dunham's mother fell asleep, Dunham and the defendant wrapped Bouchard's body in a blanket, loaded her into Dunham's brother's truck, and dumped her body into Nantucket Harbor. After they were done, the two returned to the crime scene and ingested more heroin. Bouchard's body was discovered floating in the harbor the next day.

The investigation quickly focused on the defendant and Dunham. Dunham confessed and, pursuant to a plea agreement, testified against the defendant.

The juror. The defendant challenges the judge's failure to exclude a juror for cause because that juror admitted knowing the victim casually; they both lived on Nantucket, and had gone to high school at the same time. During the voir dire, the judge called the juror to the bench and asked how well she knew the victim. The juror responded: "We were going to school about the same time as each other. I didn't know her well enough to

Page 711

have her over for dinner, but I knew who she was. . . . But, you know, to pass on the street and say hello -- that type of 'know'; not close acquaintances." Twice the judge asked whether there was any reason in her mind to think that she could not be a fair and impartial juror, and twice she affirmed that she could be fair. The judge seated the juror over the defense's objection. [Note 2]

The Sixth Amendment to the United States Constitution and art. 12 of the Massachusetts Declaration of Rights guarantee a criminal defendant the right to an impartial jury. See Commonwealth v. Seabrooks, 433 Mass. 439 , 442 (2001). General Laws c. 234, § 28, requires that a trial judge ask prospective jurors a series of questions to ascertain impartiality. [Note 3] If an answer raises a concern, such as a relationship with a party, the judge must inquire further of that juror to ensure that she can be impartial. See Commonwealth v. Young, 401 Mass. 390 , 396 (1987) (statute "requires a judge to examine a juror individually and outside the presence of the other members of the venire, if it appears to the judge that the juror may be affected by an extraneous issue"). A trial judge's subsequent determination that a juror is nonetheless impartial is subject only to review for an abuse of discretion. See Commonwealth v. Amazeen, 375 Mass. 73 , 83 (1978).

Here, the juror indicated she "knew" the victim. The judge appropriately questioned her as to the nature of the relationship and her ability to remain impartial. In light of the juror's explanation that she knew the victim only by virtue of living in the same town and having attended the same high school, it was not error for the judge to rely on her representation that she

Page 712

could be impartial. "In determining whether a juror is biased, a judge may rely on the testimony of the juror." Commonwealth v. Coleman, 389 Mass. 667 , 676 n.7 (1983). "[W]e will not conclude that the judge abused his discretion by empanelling [a] juror unless juror prejudice is manifest." Seabrooks, supra at 443. Prejudice was not manifest here, and the trial judge did not abuse his discretion by empanelling the juror. [Note 4]

Cause of death. The defendant next argues that the evidence presented by the Commonwealth was insufficient to establish causation beyond a reasonable doubt. The foundation for his argument is the testimony of the medical examiner, Dr. James Weiner. Dr. Weiner testified that the victim's blood contained potentially lethal quantities of heroin and cocaine, and that either one could have caused Bouchard's death. The defendant argues that because Bouchard's death could have resulted solely from an overdose of cocaine, as opposed to heroin, the Commonwealth did not prove causation. We disagree.

The defendant erroneously relies on the well-known and oft-cited principle that "[w]hen the evidence tends equally to sustain either of two inconsistent propositions, neither of them can be said to have been established by legitimate proof." Commonwealth v. O'Brien, 305 Mass. 393 , 400 (1940), quoting from Smith v. First Natl. Bank, 99 Mass. 605 , 612 (1868). As we explained in Commonwealth v. Latney, 44 Mass. App. Ct. 423 , 426 (1998), however, "the concept pertains only to situations in which any view of the Commonwealth's evidence, however favorable, still requires a leap of conjecture with respect to essential elements of the crime charged in order to obtain a conviction" (emphasis supplied). Thus, the principle would be applicable if, for example, the evidence showed that either the defendant or another person (the two not acting in concert) was equally likely to have provided the lethal dose of heroin. [Note 5]

Page 713

Here, viewed in a light most favorable to the Commonwealth, the defendant gave Bouchard the heroin. The medical examiner testified that the heroin by itself was potentially lethal. Thus, no "leap of conjecture" was required to prove causation, notwithstanding the existence of other possible lethal causes. "In order to be a proximate cause of death, a defendant's conduct need not be the only cause." Commonwealth v. Osachuk, 43 Mass. App. Ct. 71 , 73 (1997). See Commonwealth v. Rhoades, 379 Mass. 810 , 825 (1980). See also Commonwealth v. Maynard, 436 Mass. 558 , 563 (2002) ("It is well established that there may be more than one proximate cause of a victim's death"); Commonwealth v. Kartell, 58 Mass. App. Ct. 428 , 431 (2003) ("If more than one cause exists, criminal responsibility for each cause is assessed separately").

The evidence, as presented, warranted verdicts of guilt. [Note 6]

Judgments affirmed.
