Details Emerge on Trump Rally Shooter Thomas Crooks

Investigation reveals shooter was not bullied, had no political manifesto, and exploited security flaws at the event.

Thomas Crooks, 20, was shot dead by Secret Service after opening fire at a Trump rally, killing one and injuring two others.
School District confirmed Crooks was not a member of the rifle team and had no record of being bullied.
Experts suggest Crooks was acting out a personal fantasy rather than a politically motivated attack.
Security lapses at the rally venue are under scrutiny, with witnesses describing the event as 'disorganized.'
Crooks practiced at a gun range weeks before the attack and used a drone to scout the rally site.
