Trump rally shooter appears to have acted alone, FBI says

The FBI said Sunday that investigators have not yet identified any ideology fueling the gunman who fired at former president Donald Trump at a packed campaign rally, and they believe he carried out the horrifying assassination attempt on his own.

The gunman was identified as 20-year-old Thomas Matthew Crooks, of Bethel Park, a strong math student in high school who was working as a nursing home employee.

Seconds after he opened fire from a rooftop outside the rally’s security perimeter Saturday evening, using an AR-style rifle that was legally purchased by his father, he was fatally shot by the Secret Service, authorities said.
