Butler County District Attorney Richard Goldinger said one person is believed to be dead and “possibly a second” is dead after an apparent assassination attempt on former President Donald Trump. ABC News is reporting that at least three people are dead, including the shooter.

Goldfinger added that the person believed to be dead was “someone in the crowd,” according to a report from WTAE. Identities of those believed killed have not been released at this time.

Goldinger told ABC News that one bystander is now “confirmed” dead, while a second has possibly been killed as well. He added that the shooter is also dead.

U.S. Rep. Dan Meuser (R-PA) was in the front row alongside Rep. Mike Kelly (R-PA) and Senate candidate Dave McCormick at the time of the incident. The congressman reported that he heard 8-10 shots and believed to see multiple people down in the front row.

McCormick confirmed Meuser’s report in a statement to Fox News, adding that he definitely saw at least one person in the crowd appeared to have been hit.

Just minutes into the former president’s speech, what sounded like gunfire erupted just after 6 p.m. Eastern Time. Secret Service agents immediately dove on the former president, who appeared to be grabbing his ear.

He was then helped to his feet by Secret Service agents before giving a thumbs up to the crowd. The president’s ear appeared to be bleeding, though it is unclear if he has sustained any additional injuries at this time.

Pennsylvania Governor Josh Shapiro said, “Violence targeted at any political party or political leader is absolutely unacceptable,” adding that he had been briefed on the situation in Butler County.

A spokesperson for Trump said, “President Trump thanks law enforcement and first responders for their quick action during this heinous act. He is fine and is being checked out at a local medical facility. More details will follow.”
