A mental health evaluation has been ordered for the third and final suspect in last year’s deadly spree of rock-throwing attacks in suburban Denver after the defense claimed his ADHD contributed to the killing and the injury of half a dozen drivers.
Joseph Koenig, 19, was set to begin his jury trial for first-degree murder in Jefferson County district court later this month when his defense requested to introduce additional evidence and expert testimony into the case for an “impaired mental condition” defense, according to court documents.
Koenig’s trial has been delayed until health officials can return a mental health evaluation to the judge determining the 19-year-old’s “mental condition.”
