Ricky Shiffer, 42, armed and wearing body armor, tried to break into the FBI Cincinnati field office, leading to a police pursuit and a lengthy standoff with law enforcement near Wilmington, Ohio, according to the Ohio State Highway Patrol. He was eventually shot and killed by officers.

The footage of the pursuit shows Warren County deputies and state troopers following Shiffer on northbound Interstate 71 just before 9:40 a.m.

About 10 minutes later, with the pursuit ongoing, the first report of shots fired comes over the cruiser's radio. The patrol has said a suspected gunshot was fired from inside Shiffer's car during the chase.

Deputies and state troopers trailed Shiffer as he exited to Ohio 73, according to the cruiser footage. The chase then ends around 9:53 a.m. on Smith Road, a narrow country road bordered by a cornfield.

Shiffer exited his vehicle and exchanged gunfire with officers on two occasions, the patrol said, adding the standoff began after Shiffer took cover behind his car.

A quick succession of gunshots can be heard shortly after the pursuit comes to a halt. "Shots fired, shots fired," states a report over the cruiser's radio.

As the shots rang out, officers took cover behind their cruisers with rifles in hand, the footage shows. Officers appear to exchange gunfire with Shiffer at 10:07 a.m. Rounds hit the door of a state patrol cruiser.

Around 3:36 p.m., Shiffer is seen on camera seated next to the driver's side door of his car, a white Ford Crown Victoria, the footage shows. He appears to take a drink and then sits motionless for several minutes before armored vehicles approach his location.

He was pronounced deceased at the scene around 3:40 p.m., officials said. No injuries to law enforcement or bystanders were reported.

Authorities have not released a possible motive for the attempted breach in Cincinnati. The incident came a day after FBI director Christopher Wray warned of online threats against agents and the Justice Department after the agency served a search warrant on Trump's Mar-a-Lago home.

A Truth Social account believed to have belonged to Shiffer had referenced the search at Mar-a-Lago. One of the last posts appeared that day: "If you don't hear from me, it is true I tried attacking the F.B.I."
