We really can’t take anything the AP says as definitely true.
I’m copying that entire AP bit here, just in case the article is revised later on and that information disappears (as we have seen happen so often in the past).
Pennsylvania Gov. Josh Shapiro on Sunday identified the rallygoer who was killed as Corey Comperatore, a former fire chief from the area, and said he “died a hero.”
“His wife shared with me that he dove on his family to protect them,” Shapiro said. He declined to discuss the condition of two others who were wounded.
The FBI identified the shooter as Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania, which is about 50 miles (80 kilometers) from the scene of the shooting. An FBI official said investigators had not yet determined a motive.
Secret Service agents fatally shot Crooks. The gunman attacked from an elevated position outside the rally venue at a farm show in Butler, the agency said.
Not long before shots rang out, rallygoers noticed a man climbing to the roof of a nearby building and warned local police, according to two law enforcement officials.
One local police officer climbed to the roof and encountered Crooks, who pointed his rifle at the officer. The officer retreated down the ladder, and Crooks quickly took a shot toward Trump, and that’s when Secret Service snipers shot him, said the officials, who spoke to The Associated Press on condition of anonymity to discuss an ongoing investigation.
The officials also told AP that bomb-making materials were found inside Crooks’ vehicle, and bomb-making materials were found at his home. Officials described the devices as “rudimentary.”
Investigators believe the weapon Crooks used was purchased by his father at least six months ago, the law enforcement officials said. Federal agents were still working to understand when and how his son obtained the gun and to gather additional information about Crooks, according to the officials.
On Sunday, the FBI said they believe Crooks acted alone and that he was not previously on the bureau’s radar. The agency is combing through his social media feeds and the shooter’s weapons but so far has not found any threatening writing or social media posts, officials said.
