no, he was bludgeoned to death with a fire extinguisher. you might be thinking of the other cop who died, the one who committed suicide afterwards. but that was probably not a pre-existing condition either. more likely it was PTSD caused by the event. and there certainly haven't been any reports indicating any pre-existing condition for him.
actually, you're probably thinking of the four rioters who died. all of their deaths were linked to pre-existing medical conditions. but you were replying to remarks about the police officer who was bludgeoned to death with a fire extinguisher. being bludgeoned to death with a fire extinguisher is not a pre-existing condition.
