After he was killed by police, the suspect who tried to force his way into the FBI field office was identified.

The man, named by the Associated Press and NBC News as Ricky Shiffer, appears to have been a prolific user of former President Donald Trump's Truth Social network.

The suspect was shot and killed by police after a stand-off that began when he tried to get into the FBI office in Cincinnati.

An account bearing Shiffer's name called for violent protest and to kill federal agents in the wake of the Mar-a-Lago raid.

"If you don't hear from me, I tried attacking the F.B.I., and they took me off the internet, or they sent the regular cops while," said one post.

The FBI raid at Mar-a-Lago was a point of contention between Trump and his allies. The agency was called for to be shut down by Rep. Marjorie Taylor-Greene.

Insider reported that more obscure Trump supporters wanted a civil war. The posts referred to war.

The FBI director decried an increase in threats against law enforcement the day after the attack in Cincinnati.

The New York Times reported that investigators were looking into whether or not the man had ties to extremists.

The officials told the AP that he may have been involved in the riot and that he was being investigated for possible ties to the Proud Boys.

According to The Times, a picture of himself at a pro-Trump rally in Washington, DC, on the eve of the riot was posted on his Facebook page, as well as a picture of himself on the eve of the riot on his social media accounts.

He wasn't charged with anything related to the riot.

Insider requested a response from the FBI.
