The man identified as the shooter in the apparent assassination attempt of former President Donald Trump was a 20-year-old from a Pittsburgh suburb not far from the campaign rally where one attendee was killed.

Investigators were working Sunday to gather more information about Thomas Matthew Crooks of Bethel Park, Pennsylvania, who they say opened fire at the rally before being killed by Secret Service days before Trump was to accept the Republican nomination for a third time.

An FBI official said late Saturday that investigators had not yet determined a motive. Two spectators were critically injured, authorities said.
