WASHINGTON — A man who caused evacuations and an hour-long standoff with police at the Capitol when he claimed he had a bomb in his truck outside the Library of Congress pleaded guilty Friday to threatening to use an explosive.
Floyd Ray Roseberry, of Grover, North Carolina, pleaded guilty to the felony charge in federal court in Washington. He faces up to 10 years behind bars and his sentencing is scheduled for June.
An email seeking comment was sent to his attorney on Friday.
Roseberry, 52, drove a black van onto the sidewalk in front of the Library of Congress in August 2021 and began yelling at people on the street that she had a bomb. She later made the same bomb threats to police officers and professed a litany of anti-government grievances as part of a bizarre episode that she broadcast live to a Facebook audience.
Police later said they did not find a bomb, but did collect possible bomb-making materials. Roseberry gave up after about five hours.
During an initial court appearance, Roseberry told the judge that she had not taken her “mental medicine” and the judge ordered a mental competency hearing.
A psychiatrist discovered that the medication Roseberry had been taking was not effectively treating her diagnosed bipolar disorder. A trial judge later ruled that the new treatment had been effective and that Roseberry was fit to stand trial.
