Going out on a limb here: They couldn't come up with anything that would qualify as evidence in a court of law. If there were, they would have leaked it to the "narrative" media by now. (I don't call it the news media anymore.)
Interesting cast of characters there. I was not aware that Martin’s parents or his brother were witnesses to this event or do they possess ESP. There is this nagging thing called relevance about a witness. The scientific people, well, they have a legitimate role to play. I guess the 7/11 video is to begin a time line perhaps bolstered by the video from the club house. Still the facts remain, there are few if any eye ball witnesses and I don’t see any listed in the prosecution’s listing.
“Narative media”, that’s great. :^D
