Watch his brother take interviews like 20 times. You'll start to understand it is all fake. He worked for a crisis management company. His first two interviews, whilst he looks like he is on coke, he states:

"my brother, would never do this, he never had guns like this,"

...whilst he laughs.

"He would never, ever do something like this, it doesn't make sense. It wasn't him"

29 minutes later:

"Yes, my brother would do this, he had the guns and the money. Of course he did it, because it was him.

LMFAO. All fake. Why did he say All this, because he was part of something called ambiquity method in perception management tactics used by crisis management firms, which he worked for one. You create multiple conflicting narratives for people to believe.

The truth is, the conflicting narrative is intentional because the entire event was a fake psyop.
