Found the picture and some others as well but I didn't find what I was looking for. I thought he may have been wearing a watch on his right arm. Hence, left handed. I told some friends very early on in the case that I thought it would be very interesting to see the autopsy reports because I thought he was left handed. I don't know this for sure but that came to mind when the case first broke.
With only two lacerations on the face, I think most of the blows were from behind and since most of the damage is on the left side of the head, this leads me to beleive that the perp was left handed. Thought I may be able to find something but no luck. The case is coming on Greta now....
