BUTLER, Penn. – The 20-year-old who attempted to assassinate former President Trump at a July 13 rally in Butler, Pennsylvania, “carefully planned” and scoped out the Butler, Pennsylvania, rally-sight, the FBI revealed on Monday.
“We believe the subject made significant efforts to conceal his activities,” FBI officials said during a conference call.
The FBI said that Crooks engaged in “careful planning ahead of the campaign rally” prior to the fateful Trump rally that left one dead and three injured, including the former president.
Crooks’ meticulous planning included visits to the rally sight, the Butler County Fair Grounds, a week prior to the shooting.
The 20-year-old also went to a shooting range the day before the attack to practice with the same weapon he used in the attack, authorities said.

The FBI revealed that Crooks’ father, Matthew Brian Crooks, legally transferred a DPMS AR-15-style firearm with a collapsible stock to his son – the same firearm that the 20-year-old used in the shooting.
It was purchased legally by the shooter’s father in 2013, according to the FBI.
The federal agency also revealed that Crooks stockpiled guns as well as components to create explosive devices.
The FBI said that in spring 2023, over a year prior to the shooting, Crooks made 25 gun purchases using online aliases.

In the first half of 2024, the FBI said, he made six chemical precursor related purchases of material used to create explosive devices.
Crooks’ parents said that their son had a keen interest in science and had always done experiments, so the parents were not alarmed when the packages began to stack up at their modest home in Bethel Park, Pennsylvania.
