Most curious things to me:
In the first interview, he seems to be shocked that he had so many guns and says "yeah he had a few handguns, maybe, but rifles? I had no idea!"
But in this interview, he scoffs at the bump stock question "What did you think of him making that purchase" saying "Purchasing the thing to make it automatic?, well course he did!..." Backtracking.
Also, he seems to insist that he worked alone and carried this out by himself, but then when talking about automatic weapons says "Its not fun, and Steve was really beat up..." and lists several injuries that he has.
He says that he worked alone more than 30 times. Seems kind of weird he would defend him by saying he is so shocked this would happen, and at the same time coming back to insisting he had to do this by himself.
Also mentions never talking to the feds a suspicious number of times, leading me to believe he is lying.
Also mentions the 100k wire transfer to the Phillippines a super odd number of times and how its all going to Marilou and he's taking care of her cause he's a good guy...it would not surprise me if he wired the money to someone else in the Phillippines and just had her there as a cover story to avoid people digging into where the money actually went. Why would he not wire her every single dime in his bank account before doing this? To his brothers point, $100k for this guy is apparently a small amount of money.
He could just be a manic and kooky person though.
