I came across this thread on Gab, with some interesting info:

Both of Thomas Crooks parents are "behavioral counselors" and their license registration dates are just days apart. Odd. His parents have stink on them and are sheep-dipped if you ask me...Crooks classmates recount him being relentlessly bullied in school. Sounds like the perfect candidate.

In that thread, people post 2 pictures of Thomas Crooks wearing the tiny hat. The one I linked here, and this one:

On top of this, Thomas Crooks was also seen in a BlackRock ad:

solid confirmation imo

That guy looks far too normal. And he's sitting right near a girl. She'd be running away from the other guy.
