Trump assassination attempt: Graphics, maps show you what happened

An investigation continues into the attempted assassination of former President Donald Trump at a rally in Bulter, Pennsylvania, on Saturday, in which one attendee was shot and killed and two others seriously injured.

The gunman was shot and killed by Secret Service agents. The FBI later identified him as Thomas Matthew Crooks , 20, of Bethel Park, Pennsylvania, about 40 miles south of Butler. His motive is not yet known.

Details continue to emerge. Trump says a bullet pierced the upper part of his right ear before Secret Service agents hustled him off the stage and into a limousine. He was reported to be otherwise unharmed.

The gunman, who is believed to have acted alone, fired at the rally stage from a building rooftop about 150 yards away, outside the rally's security perimeter. Agents recovered an AR-style rifle from the scene.

Who shot Trump? What gun was used?

Sunday: Law enforcement sealed off the home of Thomas Matthew Crooks for investigation.

Crooks used a legally-purchased "AR-style 556 rifle," said Kevin Rojek, a special agent in charge of the FBI's Pittsburgh field office, on a call with reporters. The agent likely refers to a rifle that fires 5.56 mm ammunition, though there are some firearm models with "556" in their name.

The weapon was located next to Crooks on the scene, Rojek said.

Rojek said law enforcement located "a suspicious device" when they searched the Crooks' vehicle. The device is being analyzed at the FBI crime lab in Quantico, Virginia.

Agents also obtained a court order to examine Crooks' cellphone in hopes its contents will provide clues into the shooting.

"At this time, the information that we have indicates that the shooter acted alone and that there are currently no public safety concerns," Rojek said. Another unidentified official on the call said the FBI believes the weapon was bought by the shooter's father. The family is cooperating with the investigation, officials said.
