Shortly, Michael Hill in Florida was visiting a neighbor/friend when someone plunged a hunting knife into his skull, practically down to the hilt.
Most Internet references just refer to an “unknown assailant.” In one tv doc, there was a passing reference that the assailant was currently in prison.
I’ve been unable to find any informaton on the attack, though, not so much as to who the person was, but what was the motive: Random attack? Drug deal gone bad? No info.
