IN AFFIRMING THE MURDER CONVICTION OF A 14-YEAR-OLD, THE COURT OF APPEALS HELD THE TRIAL COURT PROPERLY EXCLUDED EXPERT TESTIMONY ABOUT ADOLESCENT BRAIN DEVELOPMENT AND BEHAVIOR (CT APP).
The Court of Appeals, in a brief memorandum, affirmed the murder conviction of a 14-year-old noting that the trial court properly excluded expert testimony about the brain development and behavior of an adolescent without a Frye hearing:
Defendant sought to introduce testimony by an expert witness, concerning the science of adolescent brain development and behavior, to assist the jury in determining whether the People had met their burden of disproving justification. The trial court denied defendant’s request, without conducting a Frye hearing … .
“[T]he admissibility and limits of expert testimony lie primarily in the sound discretion of the trial court” … . The criterion to be applied is “whether the proffered expert testimony would aid a lay jury in reaching a verdict” … . Under the particular facts of this case, the trial court did not abuse its discretion in denying defendant’s request to permit the proposed expert witness testimony.
