Forensicpathologistanon here; probable justification for suicide as manner of death: they assume he jumped off a building, thus causing 'blunt force injuries"; no way to tell if he was "pushed"- used to discuss this scenario and short of finding a handprint on the victim's back ( or video evidence), or suicide note ( which may be bogus), better to rule "undetermined" rather than suicide.
