"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."

"The parents of Donald Trump’s would-be assassin reportedly called police to report their son missing just hours before he rattled off at least three shots at the former president.
It’s unclear exactly what was said to police, but Fox News reported that 20-year-old Thomas Matthew Crooks’ parents, Mary and Matthew, told officers “they were worried” about their son and he’d disappeared unannounced.
That revelation came Wednesday night, just as other key details about Crooks’ potential motive came to light."
