PITTSBURGH — (WPXI) The FBI has identified the suspected gunman at former President Donald Trump’s rally on Saturday as a Bethel Park man. The agency identified him as Thomas Matthew Crooks, 20, and said they’re considering the shooting that injured Trump and two spectators and killed another spectator as an assassination attempt. Following the identification of Crooks as the suspected gunman, police shut down a Bethel Park roadway near where he lived. WPXI has learned Crooks had no previous criminal history, according to online court records. Voter records in Allegheny County show Crooks is a registered Republican voter. However, according to federal campaign finance records, Crooks appears to have donated $15 to the Progressive Turnout Project through the Democratic donation platform ActBlue. A spokesperson from Bethel Park Skilled Nursing and Rehabilitation Center also confirmed to Channel 11 that Crook was an employee of theirs. According to NBC News, Crooks was a member of the Clairton Sportsmen’s Club. The club has various shooting range, including a 200-yard rifle range as well as pistol ranges and indoor outdoor archery ranges. The FBI has not yet identified a motive for the shooting.
