Yep I seem to remember a video of a fight with him in it, that was out shortly after the story broke.
Based upon this DNA evidence they believe that two other people were accomplises of GZ that night. Everyone over there is all excited about this new evidence and have finally found the swabbing gun that TM was ganged up on.
Yes -- it took three people to lift the gun out of the holster and then hold the gun and pull the trigger. How the three managed to do that would be an amazing contortionist feat.
