Here's what we know about the suspected Trump rally shooter

The FBI identified 20-year-old Thomas Matthew Crooks of Bethel Park, Pa., as the suspect in Saturday's attempted assassination of former U.S. president Donald Trump at a campaign rally.

The suspect was shot and killed by the Secret Service seconds after he allegedly fired shots toward a stage where Trumpwas speaking in Butler, Pa.

The FBI said it was working to determine a motive for the attack, in which one rally attendee died and two other spectators were critically injured. Trump was shot in the ear.

State voter records show that Crooks was a registered Republican. The upcoming Nov. 5 election would have been the first time he wasold enough to vote in a presidential race.

Crooks lived about an hour away from where the shooting took place in Butler. The Federal Aviation Administration said on Sunday that it closed the airspace over Bethel Park, Pa.,for "special security reasons."

Hewas employed as a dietary aide at a nursing home at the time of the shooting, the home's administrator said in a statement.

Trump assassination attempt: How it unfolded

Using video footage and eyewitness accounts, CBC's Ellen Mauro breaks down the series of events surrounding the assassination attempt of former U.S. president Donald Trump at a campaign rally in Butler, Pennsylvania.

Crooks's father, Matthew Crooks, 53, told CNN that he was trying to figure out what happened and would wait until he spoke to law enforcement before speaking about his son.

Thomas Crooks graduated in 2022 from Bethel Park High School, according to the Pittsburgh Tribune-Review. He received a $500 "star award" from the National Math and Science Initiative, according to the newspaper.

A 2022 graduation ceremony video cited by the New York Times shows Crooks receiving his high school diploma to some applause. Video from that ceremony posted online shows Crooks with glasses in a black graduation gown and posing with a school official. Reuters could not immediately verify the authenticity of the video.

Quiet student

Jim Knapp, who retired from his job as the school counsellor at Bethel Park High School in 2022, said Crooks had always been "quiet as a church mouse," "respectful" and kept to himself, although he did have a few friends.

He rarely came across Crooks because "he wasn't a needy type kid," Knapp said. Crooks was content to occasionally eat lunch by himself in the school cafeteria, said Knapp, who would engage such students to see if they wanted company.

"Kids weren't calling him names, kids weren't bullying him," Knapp said.

Knapp said he never knew Crooks to be political in any way, even as other kids would sometimes wear Trump or Biden attire. He added that he couldn't recall Crooks ever being disciplined in school.

Witnesses at Trump rally shooting still reeling

As officials try to piece together the motive of the man who tried to kill Donald Trump, people in the crowd that day are still trying to process what they witnessed, with some claiming online that they had seen the gunman and tried to alert police to his presence before he pulled the trigger.

Law enforcement officials said on Saturday that Crooks carried no identification to the site of the shooting and had to be identified using other methods.

"We're looking at photographs right now and we're trying to run his DNA and get biometric confirmation," Kevin Rojek, FBI special agent in charge, said during anewsbriefing.

'AR-style' weapon reportedly recovered

Law enforcement vehicles were stationed outside a residence listed at the address on Crooks's voter registration record. Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) were on the scene Sunday and a bomb squad was at the residence, USA Today reported.

Law enforcement officials told The Associated Pressthat bomb-making materials were found inside the vehicle of the suspect and inside his home inBethel Park, about 85 kilometres south of Trump's campaign stop.

Law enforcement also recovered an "AR-style" rifle at the scene ofthe attempted assassination, according to a person familiar with the matter who spoke to The Associated Press on condition of anonymity to discuss the investigation.

Witnesses say the shots fired at former U.S. president Donald Trump appeared to come from outside the area secured by the Secret Service. The FBI said it had taken the lead in investigating the attack.

Investigators believe the weapon used in the shooting had been purchased by Crooks's father at least six months ago, the law enforcement officials said.

"It's insanity that anyone would do this,"Dan Maloney, a 30-year-old resident from the area, was quoted as saying by USA Today.

Reuters could not immediately identify social media accounts or other online postings by Crooks. Meta, the parent company of Facebook and Instagram, did not immediately respond to questions on whether the platforms had removed any accounts related to the suspect.
