What we know about Donald Trump shooting suspect

The FBI has named the man who shot at Donald Trump during a campaign rally as Thomas Matthew Crooks.

Crooks is alleged to have opened fire while the former US president was addressing a crowd in Butler, Pennsylvania, leaving one audience member dead and two others badly hurt.

The 20-year-old kitchen worker was shot dead at the scene by a Secret Service sniper, officials said.

In a statement, the FBI said Crooks was the “subject involved” in the assassination attempt on the former president and that an active investigation was under way.

Thomas Crooks had not been carrying ID, so investigators used DNA to identify him, the FBI said.

He was from Bethel Park in Pennsylvania, about 70km (43 miles) from the site of the attempted assassination, and graduated in 2022 from Bethel Park High School with a $500 prize for maths and science, according to a local newspaper.

Crooks worked in a local nursing home kitchen just a short drive away from his home, the BBC understands.

State voter records show that he was a registered Republican, according to US media.

He is also reported to have donated $15 to liberal campaign group ActBlue in 2021.

According to US media reports, Crooks was wearing a T-shirt from Demolition Ranch, a YouTube channel known for its guns and demolition content. The channel has millions of subscribers featuring videos on different guns and explosive devices.

Law enforcement officials believe the weapon used to shoot at Donald Trump was purchased by Crook’s father, the Associated Press news agency reports.

Speaking on condition of anonymity, two officers told AP that Crooks’ father bought a weapon at least six months ago.

The day after the shooting, law enforcement sources also told CBS, the BBC’s US partner, that suspicious devices were found in Crooks’ vehicle.

According to CBS, the suspect had a piece of commercially available equipment that appeared capable of initiating the devices.

Bomb technicians were called to the scene to secure and investigate the devices.

Having established Crooks’s identity, police and agencies are investigating his motive.

“We do not currently have an identified motive,” said Kevin Rojek, FBI Pittsburgh special agent in charge, at a briefing on Saturday night.

The inquiry into what took place could last for months and investigators would work “tirelessly” to identify what Crooks’ motive was, Mr Rojek said.

Speaking to CNN, Crooks’ father, Matthew Crooks, said he was trying to figure out “what the hell is going on” but would “wait until I talk to law enforcement” before speaking about his son.

Police sealed off the road to the house where Crooks lived with his parents, CBS News reports.

A neighbour told CBS that officers evacuated her in the middle of the night with no warning.

Bethel Park Police said there was a bomb investigation surrounding Crooks’s home.

Access to the area remains tightly controlled with police vehicles blocking the roads. Only residents have been allowed in or out.

Law enforcement sources told CBS that they believe some degree of planning ahead of the shooting.

How much time was spent in that planning, however, remains the subject of an ongoing investigation.

Police believe he acted alone, but are continuing to investigate whether he was accompanied to the rally.

One person was killed and two others were injured in the shooting.

All three victims are adult men and were audience members, CBS News reports. Their names have not been released.

A GoFundMe page, organised by the Trump campaign’s national finance director Meredith O’Rourke, was set up in the hours after the attack with donations going to the families of the injured.

It has so far raised more than $340,000 (£267,000).

In a post to his Truth Social platform, Trump said he was “shot with a bullet that pierced the upper part of my right ear” and said he felt the bullet “ripping through the skin”.

Blood was visible on Trump’s ear and face as protection officers rushed him away.

Trump is “doing well” and is grateful to law enforcement officers, according to a statement published on the Republican National Committee (RNC) website.

One witness told the BBC that he had seen a man – believed to be Crooks – with a rifle on the roof of a building before Trump was shot at.

Video footage obtained by TMZ shows the moment the shooting began.

The assailant opened fire with “an AR-style rifle”, CBS News reports.

Law enforcement sources also told CBS that he was reported by a bystander and identified as a suspicious person by police, but that officers lost track of him before the shooting began.

However, the FBI says it did not immediately know what type of firearm the gunman used or how many shots were fired.

A Secret Service sniper returned fire and killed the gunman, the agency said.

Footage later shows armed officers approaching a body on the roof of the building.
