Gray Hughes made some "interesting" videos about this case. I don't agree with everything that he says/thinks about this case, but some of the videos are interesting. I don't believe that the gun shot came first.

(Not to my knowledge is Gray Hughes related to the Hughes that were friends of TA's.)
