Dutch was among three rally-goers who were shot during the assassination attempt of former President Trump on July 13. One person, 50-year-old Corey Comperatore, of Sarver, was killed.

Comperatore was a firefighter who leaves behind a wife and two daughters.

Officials say Comperatore was shielding his family when he was fatally struck by a bullet.

Comperatore "died a hero" when he "dove on his family" to protect them from the gunfire during the rally, his wife told Pennsylvania Governor Josh Shapiro.

The two people who were critically wounded in the assassination attempt on former President Donald Trump have been identified.

The second surviving victim, 74-year-old James Copenhaver, of Moon Township, is still in the hospital. He is said to be in serious but stable condition.

"We pray for the recovery of those who were wounded, and hold in our hearts the memory of the citizen who was so horribly killed," Trump wrote on TruthSocial after the attempt on his life.

The gunman has been identified as 20-year-old Thomas Matthew Crooks , of Bethel Park, Pa.

FBI Director Christopher Wray said there is no apparent motive yet.

In the wake of the failed assassination attempt, the Secret Service and FBI have come under scrutiny for not preventing the attack.

In an interview with ABC News after the attack, U.S. Secret Service Director Kimberly Cheatle called the incident "unacceptable" and said it was her responsibility to ensure nothing like it would happen again.

"The buck stops with me," she said. "I am the director of the Secret Service, and I need to make sure that we are performing a review and that we are giving resources to our personnel as necessary."

Since then, Cheatle has resigned.

"The Secret Service's solemn mission is to protect our nation's leaders and financial infrastructure. On July 13th, we fell short on that mission," she wrote. "The scrutiny over the last week has been intense and will continue to remain as our operational tempo increases. As your Director, I take full responsibility for the security lapse."
