In Bethel Park, where the man who is suspected of opening fire at a Donald Trump campaign rally on Saturday lived with his mother and sister, the houses are small and built of brick, Walmart and Target form central social hubs, and moms watch over their children at a junior league baseball park next to a tributary of the Allegheny River.
The attempted assassination of the Republican former president just 45 miles north has put a focus on Bethel Park, as investigators attempt to establish the motivations of the 20-year-old shooter.
Authorities on Sunday identified the suspect as Thomas Matthew Crooks. Officials said they believe Crooks acted alone. But so far, they have not been able to uncover a motivation that drove the young man to unleash a hail of bullets at Trump, wounding the former president and killing a former fire chief who was shielding his daughters.
The FBI said it would continue to investigate the attack as an attempted assassination and an act of domestic terrorism.
Claire, a young woman who had known Crooks through his elder sister and who did not provide a last name, said she could not quite believe the boy she had once known had attempted to assassinate a US president.
