Investigators were hunting for any clues about what may have driven Thomas Matthew Crooks,of Bethel Park,Pennsylvania,to carry out the shocking attack that killed a spectator. The FBI said it was investigating the shooting as a potential act of domestic terrorism,but the absence of a clear ideological motive by the man shot dead by Secret Service led conspiracy theories to flourish.

“I urge everyone – everyone,please,don’t make assumptions about his motives or his affiliations,” President Joe Biden said in remarks from the White House. “Let the FBI do their job,and their partner agencies do their job. I’ve instructed that this investigation be thorough and swift.”
The FBI said it believes Crooks,who had bomb-making materials in the car he drove to the rally,acted alone. Investigators have found no threatening comments on social media accounts or ideological positions that could help explain what led him to target Trump before Secret Service rushed the presumptive Republican presidential nominee off the stage,his face smeared with blood.
Relatives of Crooks didn’t respond to numerous messages from The Associated Press. His father,Matthew Crooks,told CNN late on Saturday that he was trying to figure out “what the hell is going on” but wouldn’t speak about his son until after he talked to law enforcement. An FBI official told reporters that Crooks’ family was co-operating with investigators.
Several people at the rally reported to local officers that Crooks was acting suspiciously and pacing near magnetometers in place to detect metal objects,according to a law enforcement official who spoke on the condition of anonymity because they were not authorised to discuss the investigation. Officers were then told Crooks was climbing a ladder,the official said. Officers searched for him but were unable to find him before he made it to the roof,the official added.

Butler County Sheriff Michael Slupe said that a local officer climbed to the roof and encountered Crooks,who saw the officer and turned toward him just before the officer dropped down to safety. Slupe said the officer couldn’t have wielded his own gun under the circumstances. The officer retreated down the ladder,and Crooks quickly took a shot towards Trump,and that’s when Secret Service snipers shot him,according to two officials who spoke to the AP on condition of anonymity to discuss an ongoing investigation.
FBI officials said that they were combing Crooks’ background and social media activities while working to get access to his phone. The chatting app Discord,a social media platform popular with people playing online games,said Crooks appeared to have had an account but used it rarely and not in the past several months. There’s no evidence he used his account to promote violence or discuss his political views,a Discord spokesperson said.
Crooks’ political leanings were not immediately clear. Records show he was registered as a Republican voter in Pennsylvania,but federal campaign finance reports also show he gave $US15 ($22) to a progressive political action committee on January 20,2021,the day Biden was sworn into office.
Crooks graduated from Bethel Park High School in 2022. In a video of the school’s graduation ceremony posted online,Crooks can be seen crossing the stage to receive his diploma,appearing slight of build and wearing glasses. The school district said it will co-operate fully with investigators. His senior year,Crooks was among several students given an award for math and science,according to a Tribune-Review story at the time.

Crooks tried out for the school’s rifle team but was turned away because he was a bad shooter,said Frederick Mach,a current captain of the team who was a few years behind Crooks at the school. He was a member of a local shooting club named Clairton Sportsmen’s Club,the club confirmed to the media while condemning the shooting and calling it a “senseless act of violence”.
Jason Kohler,who said he attended the same high school but did not share any classes with Crooks,said Crooks was bullied at school and sat alone at lunchtime. Other students mocked him for the clothes he wore,which included hunting outfits,Kohler said.
“He was bullied almost every day,” Kohler told reporters. “He was just an outcast,and you know how kids are nowadays.”
Crooks worked at a nursing home as a dietary aide,a job that generally involves food preparation. Marcie Grimm,the administrator of Bethel Park Skilled Nursing and Rehabilitation,said in a statement she was “shocked and saddened to learn of his involvement.” Grimm added that Crooks had a clean background check when he was hired.

A blockade had been set up preventing traffic near Crooks’ house,which is in an enclave of modest brick houses in the hills outside Pittsburgh and about an hour’s drive from the site of the Trump rally. Police cars were stationed at an intersection near the house and officers were seen walking through the neighbourhood.
Crooks used an AR-style rifle,which authorities said they believe was purchased by his father. Kevin Rojek,FBI special agent in charge in Pittsburgh,said that investigators do not yet know if he took the gun without his father’s permission.
A video posted to social media shows Crooks wearing a grey t-shirt with a black American flag on the right arm lying motionless on the roof of a manufacturing plant just north of the Butler Farm Show grounds where Trump’s rally was held.
The roof where Crooks lay was less than 150 metres from where Trump was speaking,a distance from which a decent marksman could reasonably hit a human-sized target. That is a distance at which US Army recruits must hit a scaled human-sized silhouette to qualify with the M-16 rifle.
Images of Crooks’ body reviewed by AP show he appears to have been wearing a T-shirt from Demolition Ranch,a popular YouTube channel that regularly posts videos of its creator firing off handguns and assault rifles at targets that include human mannequins.
Matt Carriker,the Texas-based creator of Demolition Ranch,did not respond to a phone message or email,but posted a photo of Crooks’ bloody corpse wearing his brand’s T-shirt on social media with the comment “What the hell.”
