Although I'm sure a lot of us have seen this terrible incident being shared around Facebook, I thought I'd help spread the word on here. Any extra publicity that this situation receives is a very good thing.
In the above article, the wife of the victim mentions how video footage suggests that the situation was predetermined between two people who created a distraction.
Several people have suggested that extra video footage might show if the thief played in any event this weekend. If he did, somebody might be able to determine what his table number was and (likely) what his name and DCI number would be from there. There haven't been any updates on this from what I've seen, so I'm afraid that he probably didn't play in any events.
With how well connected the Magic community is in 2016, I'm truly surprised that this case hasn't been wrapped up yet. With the thief's Knicks jacket, I'd have to assume that he's from New York, but that obviously doesn't give us very much information to work with. There's no way that he's completely unknown, though. The security footage just has to be seen by the right few people, I suppose. I sincerely hope we find those few people who can help.
If you suspect that you've ever seen this person before in your life, please reach out to Shaun Martin. His contact information is in the article I shared above.
