Trump shooting updates: Shooter flew drone near site hours before shooting

A Butler County resident whose house is one of the closest properties to the scene of the Trump rally shooting said she was surprised that the Secret Service did not search her home ahead of the event.

"I thought that would be something that they would do since I live so close," Carol Kerr, 82, told ABC News by phone early Sunday morning.

Kerr's house on Meridian Road is roughly a quarter of a mile from both the stage where the former president was speaking on Saturday and the location where the shooter is believed to have been firing from.

"I thought they would search the houses that are as close as mine is," Kerr said. "At least check them out and see if you have anything in your house which is dangerous, which I don't."

The FBI early on Sunday identified the suspected gunman as Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania.

"This remains an active and ongoing investigation, and anyone with information that may assist with the investigation is encouraged to submit photos or videos online at FBI.gov/butler or call 1-800-CALL-FBI," an FBI spokesperson said.

While law enforcement said at a press conference late Saturday that they believe they know who carried out the shooting, they are still not naming the individual.

Officials said they are also doing DNA testing, because the suspected shooter did not have ID.

"It's a matter of doing biometric confirmations," FBI Special Agent in Charge Kevin Rojek said. "So, there was no identification on the individual, for example, so we're looking at photographs right now and we're trying to run his DNA and get biometric confirmation."

The shooter's name will be released once there is an official confirmation, he said.
