Question will resolve positively if, in Mangione’s state trial for the alleged murder of Brian Thompson, his defense attorneys assert either the affirmative defense of extreme emotional disturbance or that he is not guilty by reason of mental illness.

There is a similar existing question that includes substance impairment and would also IMO include mental illness arguments made at sentencing. This question is intended to more narrowly focus on arguments of mental illness or extreme emotional disturbance made before a verdict.
