Suspect shot in FBI attack dies after hours-long standoff — identified as man present at the Capitol on Jan. 6

The man who allegedly attacked FBI offices in Cincinnati, Ohio, earlier on Thursday — and who was shot as police attempted to apprehend him — has died from his injuries after a shootout, law enforcement officials said. Official sources also identified him as a man who had attended the protest at the U.S. Capitol on Jan. 6.

Officials said a man tried to enter the FBI offices at about 9:15 a.m. but was unsuccessful and fled the area.

Later, an Ohio state trooper spotted the suspect's car and tried to initiate a stop that led to a chase.

“The suspect vehicle did fire shots during that pursuit,” said Lt. Nathan Dennis to reporters. “Gunfire was exchanged between officers on scene and the suspect."

CNN reported that a source told them law enforcement believed he was armed with an AR-15 and a nail gun. One report said that he had been wearing body armor and fired the nail gun into the building.

Police set a perimeter around the suspect's car after it came to a stop in in Clinton County, north of the FBI offices.

Officials said they negotiated with him for about 6 hours before they moved in after those negotiations failed. They said he raised his gun and pointed at them before they shot and killed him.

Law enforcement officials confirmed to NBC News that they had identified the man as Ricky Walter Shiffer and that he had been present at the U.S. Capitol on Jan. 6.

Also on Thursday, U.S. Attorney General Merrick Garland announced in a media briefing that the Department of Justice would be seeking the release of the search warrant involved in the Mar-a-Lago raid. He also admitted that he had personally signed off on the search warrant at former President Donald Trump's Florida residence.

Many on the left have criticized overheated rhetoric against the FBI by those angry over the bureau's actions at Mar-a-Lago.

FBI Director Christopher Wray defended the department's actions in an email to employees.

“There has been a lot of commentary about the FBI this week questioning our work and motives,” Wray said. “Much of it is from critics and pundits on the outside 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 doing their jobs professionally and by the book every day; this week is no exception.”
