 Crooks' high school years were troubled, and he was rejected by the school rifle team. He was also bullied at school and sat by himself, friendless, in the cafeteria at lunch. The motive for firing at Trump remains a mystery. When 20-year-old Crooks was taken down by a Secret Service sniper, he wore a T-shirt from Demolition Ranch, a YouTube channel that features firearms. Authorities say they found rudimentary explosive devices in his car and at his home.
