Armed man who tried to breach FBI Ohio office killed after six-hour standoff with police

CINCINNATI - An armed suspect who tried to breach a secure area at the FBI field office in Ohio, led police on a chase, and exchanged gunfire with officers was shot and killed by police after an hourslong standoff, Ohio Highway State Patrol said.  

Multiple reports have identified the suspect as Ricky Walter Shiffer. Law enforcement is reportedly investigating whether he was involved in the Jan. 6, 2021 riot at the U.S. Capitol. 

The suspect was shot after he raised a gun toward police, patrol spokesperson Lt. Nathan Dennis said during a press conference. 

Multiple federal, state, and law enforcement agencies were on scene where a standoff with the suspect was underway, Ohio State Highway Patrol tweeted earlier. 

The standoff with the armed suspect, who was wearing body armor, lasted for more than six hours in a rural field in Wilmington, Ohio. It wasn't immediately clear whether the suspect was in custody.

A spokesperson for Ohio State Highway Patrol or the FBI Cincinnati office could not be reached for comment. 

Ohio State Highway Patrol said it responded to Interstate 71 in an attempt to locate an armed suspect who fled from the FBI Cincinnati Field Office. 

At approximately 9 a.m., an armed subject attempted to breach the Visitor Screening Facility at FBI Cincinnati, according to tweet from FBI Cincinnati's account. 

Unconfirmed information shared internally among agents suggested the suspect possibly brandished a nail gun and an AR-15 style rifle, the source said.

Troopers located the suspect's vehicle, a Ford Crown Victoria, near the northbound Interstate 71 rest area in Warren County around 9:37 a.m.

Law enforcement pursued, and the suspect traveled about 60 miles northwest before the pursuit ended at I-71 and Hwy 73.

State Highway Patrol said shots were fired from within the suspect's vehicle. The pursuit continued on Interstate 71 until the suspect exited at state Route 73, traveling eastbound before turning onto Smith Road, Ohio State Highway Patrol said. 

The suspect's vehicle came to a stop around 9:53 a.m. on Smith Road near Van Trees Road in Clinton County. Ohio State Highway Patrol said the suspect exited the vehicle and exchanged gunfire with officers.
