 Let me help you. The guy had spun around, was jammed between the benches. He had a headshot here. There was lots of blood, and he had brain matter there. Law enforcement has identified the shooter as 20-year-old Thomas Matthew Crooks of nearby Bethel Park, Pennsylvania, seen here accepting his high school diploma in 2022. One attendee told the BBC that he'd seen the man and notified law enforcement on the scene prior to the shooting. We noticed the guy crawling around.
