The FBI identified 20-year-old Thomas Matthew Crooks as the shooter in former President Donald Trump’s apparent assassination attempt on July 13 in Butler, Pennsylvania. Crooks was killed by the Secret Service at the scene. In the hours following the rally, photos purporting to be of the suspected shooter went viral online. Here is what we do know about Crooks. The FBI identified the suspected shooter as Thomas Matthew Crooks early on July 14, hours after the shooting. Authorities told reporters that Crooks was not carrying identification so they used DNA and other methods to confirm his identity. The FBI has not revealed a motive for the shooting and believe Crooks acted alone. Law enforcement sources told multiple news outlets they recovered an AR-style rifle at the scene. Those sources also said the gun appears to be registered in the name of Crooks’ father. The FBI says they also found a “rudimentary” suspected explosive device in the car Crooks was using and other suspicious devices at his home. The Pentagon confirmed Crooks doesn’t have a military background. Federal campaign finance reports show that when Crooks was 17 he donated $15 to Act Blue -- a progressive political action committee on Jan. 20, 2021, the day President Joe Biden was sworn into office. Pennsylvania voting records show Crooks later registered as a Republican. November would have been the first presidential election he was eligible to vote in. Crooks graduated from Bethel Park High School in 2022, the school district said in a statement given to KDKA-TV. The school district said it will cooperate fully with investigators.
