I would think there would have been defensive wounds if TM was trying to get away, trying to defend himself from GZ. Some theorize GZ was holding onto TM, on top of him - IMO, there'd be something.
Per the person who prepped the body for burial, there were none. Oddly enough, the pro TM folks are using this to "prove" that TM didn't attack GZ. Not really understanding that, but it is what it is. :waitasec:
