Lieutenant Nathan Dennis said after the negotiations failed, law enforcement officers tried to take the suspect into custody, but the suspect raised a gun at authorities and was fatally shot.
The man was identified as Ricky Shiffer, according to three federal law enforcement sources.
The FBI is investigating Shiffer’s social media presence and whether he had links to right-wing extremism, one of the sources said.
The hours-long stalemate followed a chase with the suspect.
Earlier, Dennis said an armed man attempted to enter the FBI’s Cincinnati office around 9:15 a.m. ET on Thursday morning. However, the suspect was unsuccessful and fled the area.
An Ohio state officer spotted the suspect’s vehicle at a rest stop northbound off Interstate 71 about 20 minutes after the attempted break-in, Dennis said, and attempted to initiate a traffic stop before the suspect fled.
“The suspicious vehicle fired during that chase,” Dennis said at the earlier press conference. The suspect then left State Route 73 and traveled east to Smith Road, where it turned north before finally coming to a stop.
“Gunfire has been exchanged between officers at the scene and the suspect,” Dennis said.
No officers had been injured at the time of the press conference, Dennis said.
The FBI said “an armed subject tried” to breach the facility’s visitor screening facility.
“After triggering an alarm and a response from FBI special agents, the subject fled north on Interstate 71,” the statement said. “The FBI, Ohio State Highway Patrol and local law enforcement partners are on the scene near Wilmington, OH to resolve this critical incident.”
A federal law enforcement source told DailyExpertNews the suspect was believed to have been armed with a nail gun and AR-15. Another federal law enforcement source with knowledge of the incident told DailyExpertNews that FBI facilities across the country are reviewing their security stance in the wake of the incident.
In a report reviewed by DailyExpertNews on Thursday, FBI Director Chris Wray told agency employees that their “safety and security” was his “primary concern” right now.
“There has been a lot of commentary this week about the FBI questioning our work and our motives,” Wray said. “A lot of it comes from outside critics and experts who don’t know what we know and don’t see what we see. What I know – and what I see – is an organization made up of men and women who are committed to their work every day. professionally and by the book; this week is no exception.”
