A gunman was shot and killed by the police following an hourslong standoff after trying to breach the F.B.I.’s Cincinnati office, officials said.
Authorities said the man was wearing body armor and fled to Clinton County, Ohio, where he hid in a cornfield after exchanging gunfire with the police, and refused to surrender. Investigators are said to be looking into whether the man had ties to extremist groups.
The confrontation came as officials warned of an increase in threats against federal agents in the days following a search of former President Donald Trump’s Mar-a-Lago estate in Florida.
The man is believed to have been in Washington in the days leading up to the Jan. 6, 2021 insurrection and may have been present at the Capitol on the day of the attack, according to a law enforcement official briefed on the matter. The official could not discuss details of the investigation publicly and spoke on condition of anonymity.
