Thomas Matthew Crooks, a 20-year-old man, attempted to assassinate former President Donald Trump at a rally in Butler, Pennsylvania, injuring Trump and killing one attendee. Prior to the attack, Crooks engaged in suspicious activities, including visiting a shooting range, purchasing a ladder, and acquiring ammunition and an improvised explosive device. Despite thorough investigations, including searches of his phone, computer, and interviews with over 100 people, a clear motive remains elusive. Crooks was described as an intelligent loner with a thin social media presence and no strong political beliefs. His father, a pro-gun voter profiled by Trump’s 2016 campaign, legally purchased the rifle used in the attack. The incident has raised questions about security lapses and the enigmatic nature of Crooks’ motives.
