Video shows passersby trying to alert police to shooter at Trump rally

A video taken by a passerby outside Donald Trump’s campaign rally in western Pennsylvania on July 13 shows the suspected shooter on the roof of a building next to the venue.

One person was killed and two others were seriously injured when a gunman opened fire while former President Donald Trump was speaking on stage. Trump, 78, suffered a minor injury in what was ruled an attempted assassination but was safely evacuated by Secret Service agents.

The suspected shooter, 20-year-old Thomas Matthew Crooks, was subsequently killed.

A bystander’s video shared by NBC News on Instagram shows Crooks climbing onto the roof, from where he presumably fired the shot.

Several people can be heard pointing at the man and at least two people are calling him to a police officer. A weapon is not visible in the video.

“Officer, he’s on the roof,” a woman is heard saying. “Right here, flat on the roof.”

Crooks was able to fire several shots before he was killed. The FBI is investigating the shooting and is still trying to determine Crooks’ motive.

In conversation with George Stephanopoulos about Good morning America, Alejandro Mayorkas, Secretary of Homeland Security, said: “Such a direct line of sight with the former president should not be possible.”

Mayorkas also said President Joe Biden had ordered an “independent investigation into the incident.”

“We need to know everything we can about the attacker that the Secret Service, of course, so bravely and heroically neutralized, and we will truly independently investigate the incident and make recommendations to the Secret Service and to me so that we can ensure the safety of our protected individuals, which is one of our most important missions in the Secret Service, the Department of Homeland Security and across the government,” Mayorkas said on GMA.

Corey Comperatore, 50, a firefighter from Sarver, Pennsylvania, was killed in the shooting. Two other men, David Dutch, 57, and James Copenhaver, 74, were both seriously injured.
