The Massachusetts Supreme Judicial Court heard oral argument in the case of Commonwealth v. Jesse Carrillo, where the defendant was convicted of involuntary manslaughter based on providing heroin to the deceased. The defendant was a heroin addict himself and the evidence at trial indicated that he went to New York to boy heroin and that he would bring some heroin back to the victim.
At trial the defendant was convicted of both distribution of heroin and involuntary manslaughter. The defendant claimed that the trial court committed reversible error by refusing to instruct the jury on the lesser included offense of joint possession of heroin. It was the defendant’s claim throughout the trial that he was a user and an addict but was not distributing heroin or making any profit from selling heroin. The defendant testified in his own defense at the trial and outlined his heroin addiction. The defendant also presented expert testimony.
