So after looking at some of the photos, I am left thinking of a question we've had for some time and that is, was the button really found on TM's sweatshirt or in his pockets by police or ME? In looking at the photo's from the 7-11 and the photo of the sweatshirt with the gunshot wound, it looks like the button would have been awfully darn close to the bullet hole. I am not suggesting I can tell its exactly where the bullet hole is or that even if it was, the gun could have been under the button when the shot was fired. However, if the button were on TM's person, in the location that it can be seen on the 7-11 photos, it most certainly would have had blood on it and likely gunshot residue.
Was the button tested for any forensics evidence? I don't recall that it was, but can't think of any reason it wouldn't have been tested if found on the sweatshirt right by the gunshot wound. IT seems to me that if it wasn't tested, then it wasn't in the same location that it was on while at the 7-11 and most likely was not attached to the sweatshirt. That, or police just totally screwed that one up.
