Newly released police bodycam video from the Trump assassination attempt shows police discovering a transmitter for an explosive device next to the shooter's dead body.
The dramatic video also shows police and a Secret Service agent identifying the dead shooter as the same man who was photographed acting suspiciously before the attack.
The video was recorded by a Beaver County Emergency Services Unit officer and shared with Republican Senator Chuck Grassley (IA).
In the video, officers are seen rushing to access the rooftop that Thomas Matthew Crooks used to shoot at Trump.
A trail of blood is seen on the roof leading to Crooks' body. Next to his body, police make a troubling discovery: an electronic transmitter.
"It is a remote control device. It is gray in color, about five, six inches tall," an officer says, urging the FBI to "hurry the (expletive) up."
FBI director Christopher Wray told Congress Wednesday that Crooks had two explosive devices in his car and another at home.
It's unclear why the bombs were left in his car, but Wray said they were capable of being blown up remotely.
Secret Service has faced scrutiny for its failure to secure the rooftop, as well as its response to numerous warnings of suspicious activity before the shooting. A Beaver County sniper noticed a suspicious man using a rangefinder on the ground and took a photo.
The bodycam video shows Secret Service and police confirming that the dead body matches the man in the photo.
"A Beaver County sniper seen and sent the pictures out, this is him," the officer with the bodycam says.
"I don't know if you got the same ones I did?" the officer asks the Secret Service agent.
"I think I did, yeah, he's got his glasses on," the agent replies.
The men also discuss a suspicious abandoned bike. The officer says the sniper saw the shooter walk from the bike and set a bag down, then "lost sight of him."
FBI director Wray told Congress that Crooks had a collapsible stock, which made it easier to conceal his gun. He may have accessed the rooftop by climbing pipes.
Wray also said Crooks used a drone to scout the area two hours before the shooting. The drone would have given Crooks a view of the area behind him when he was on the rooftop.
