Trump shooter's parents called police hours before assassination attempt

Thomas Matthew Crooks' parents contacted law enforcement Saturday hours before he opened fire on former President Trump at a Pennsylvania campaign rally, a source told Fox News. 

The aspiring assassin's mother and father told local police that Crooks was missing and that they were concerned about his welfare, the source said.

It remained unclear if they knew that he was in possession of an AR-15 rifle that belonged to his father.

Police have not said what actions they took after being contacted.

Crooks' parents are cooperating with FBI investigators as the agency tries to specify a motive for the shooting that injured Trump and killed rally attendee Corey Comperatore.

Officials completed a vetting of Crooks' phone and social media accounts, but have yet to publicize the results of that probe.

The shooter's parents, Matthew and Mary Crooks, were both licensed as professional counselors in Pennsylvania, according to state records.

They both received their social work licenses in 2002 and renewed them as recently as last year.
