Buffalo Township, Pennsylvania — 

The former fire chief who was killed at a Pennsylvania rally for Donald Trump spent his final moments diving down in front of his family, protecting them from gunfire on Saturday during an assassination attempt against the former president.

Corey Comperatore's quick decision to use his body as a shield against the bullets flying toward his wife and daughter rang true to the close friends and neighbors who loved and respected the proud 50-year-old Trump supporter, noting that the Butler County resident was a "man of conviction."

"He's a literal hero. He shoved his family out of the way, and he got killed for them," said Mike Morehouse, who lived next to Comperatore for the last eight years. "He's a hero that I was happy to have as a neighbor."

Comperatore died Saturday during what is being investigated as an attempted assassination of Trump at a campaign rally in Butler, Pennsylvania. At least two other people were injured: David Dutch, 57, of New Kensington, Pennsylvania, and James Copenhaver, 74, of Moon Township, Pennsylvania, according to the Pennsylvania State Police. Both were listed in stable condition as of Sunday.

As support for Comperatore's family began to pour in from across the country, President Joe Biden and first lady Jill Biden also extended their "deepest condolences."

"He was a father. He was protecting his family from the bullets that were being fired and he lost his life, God love him," said Biden, who added he was praying for the full recovery of the wounded.

Separately, Texas U.S. Rep. Ronny Jackson said in a statement Sunday that his nephew was injured but "thankfully his injury was not serious."

"My family was sitting in the front, near where the President was speaking," Jackson said. "They heard shots ringing out — my nephew then realized he had blood on his neck and something had grazed and cut his neck. He was treated by the providers in the medical tent."

The Secret Service said it killed the suspected shooter, who attacked from an elevated position outside the rally venue.

The former president was showing off a chart of border-crossing numbers when at least five shots were fired. Trump was seen holding his ear and got down on the ground. Agents quickly huddled in a shield around him. When he stood, his face bloodied, he pumped his fist to cheering supporters as he was whisked off stage by Secret Service agents.

Trump later extended his condolences to Comperatore's family.

Randy Reamer, president of the Buffalo Township volunteer fire company, called Comperatore "a stand-up guy" and "a true brother of the fire service." He said Comperatore served as chief of the company for about three years but was also a life member, meaning he had served for more than 20 years.

"Just a great all-around guy, always willing to help someone out," Reamer said of Comperatore. "He definitely stood up for what he believed in, never backed down to anyone. … He was a really good guy."

A crew was power-washing the front of the Buffalo Township Volunteer Fire Company on Sunday with plans to install memorial drapery to honor the slain former chief.

Assistant Chief Ricky Heasley of Sarver, who knew Comperatore for more than a decade, remembered him as very outgoing and full of life.

"He never had a bad word," Heasley said.

And in the front yard of the Comperatores' two-story home in Butler County, a small memorial had sprung up of a U.S. flag and small bunches of flowers.

For Morehouse, Comperatore's death was an emotional blow — but it also has inspired political action. Morehouse says he plans on casting a ballot for the first time in his life come November and he plans on checking Trump's name.

"As soon as I heard what happened and then learned that it was to Corey, I went upstairs as soon as I got home and I registered to vote," Morehouse said. "This is the first time I've ever voted, and I think it will be in his memory."

A GoFundMe launched to support Comperatore's family had surpassed more than $480,000 in donations as of Sunday.
