Here’s what we know about the attempted crime and the suspect:
What happened when the suspect tried to enter the office
At around 9:15 a.m. ET Thursday, a gunman attempted to enter the FBI’s field office visitor screening facility, the agency said.
“After an alarm was activated and a response from armed FBI special agents, subject fled north on Interstate 71,” FBI Cincinnati said in a statement.
Ohio State Highway Patrol troopers responded and found the suspect at an interstate rest area in a Ford Crown Victoria around 9:37 a.m., the patrol said.
Troopers attempted to intercept the suspect, but he fled and a vehicle chase ensued, Highway Patrol spokesman Lt. Nathan Dennis said. Shots were fired from the suspect’s car during the chase, he said.
The suspect pulled off the freeway at State Route 73 in Clinton County, Ohio — about a 45-mile drive northeast of downtown Cincinnati — and stopped on a nearby road toward 9:53 a.m., Highway Patrol said.
How the standoff unfolded
After pulling over, the man got out and “engaged officers,” the highway patrol said. Gunfire was exchanged between law enforcement and the suspect, who used his vehicle for cover, they said.
The standoff lasted for several hours as law enforcement tried to negotiate with the suspect, Highway Patrol said.
“Once negotiations failed, officers attempted to take the suspect into custody using less lethal tactics,” the agency said. “At approximately 3:42 p.m. the suspect raised a gun and shots were fired by law enforcement.”
The suspect was shot and died of his injuries at the scene, the agency said.
It is unclear what less lethal tactics authorities used when trying to arrest him.
What we know about the suspect
The FBI is investigating Shiffer’s social media presence and ties to right-wing extremism, a federal law enforcement source told CNN.
The post was posted minutes after the Ohio State Highway Patrol said the incident at the Cincinnati office began, shortly after 9:15 a.m.
“Well, I thought I had a way through the bulletproof glass, and I don’t,” the user said at 9:29 a.m. Thursday. “If you haven’t heard from me, it’s true that I tried to attack the FBI, and that either means I got taken off the internet or the FBI got me, or they sent in the regular cops during that time.”
It’s not clear if the user was attempting to write more, as the message stops after “while”.
The FBI declined to comment on the account and its posts, citing an ongoing investigation.
“People, this is it,” the user wrote on Monday. “I’m hoping a call to arms will come from someone more qualified, but if not, it’s your call to arms from me.”
In that post, the user encouraged people to visit gun and pawn shops to “get everything you need to be battle ready.”
When another person replied to the user saying they would send their photo and information to the FBI, the user responded by saying, “Bring them.”
It is not known whether the information was passed on to the FBI.
On Tuesday, the user wrote that the people were heading to Palm Beach, Florida — where Mar-a-Lago is — and said if the FBI disperses the group, “kill them.”
How the FBI responded
FBI headquarters is investigating the “agent-involved shooting,” the agency said. The agency deployed a shooting incident review team to the scene, which is standard practice when an FBI special agent or task force officer discharges a weapon, a law enforcement source told CNN.
The review team will gather evidence, interview witnesses and ultimately determine whether the use of lethal force was justified, the source said.
“The FBI takes all shooting incidents involving our agents or members of the task force seriously,” a statement from the office read. “The review process is thorough and objective, and is conducted as expeditiously as possible under the circumstances.”
FBI Director Christopher Wray released a statement Thursday evening condemning the attacks on law enforcement and the FBI.
“The baseless attacks on the integrity of the FBI undermine respect for the rule of law and do grave harm to the men and women who sacrifice so much to protect others. The violence and threats against law enforcement, including the FBI, are dangerous and should be of deep concern to all Americans,” Wray said.
