Last week, 52-year-old Floyd Ray Roseberry pled guilty to one charge of threatening to use explosives. He made this treat during a four-hour standoff with law enforcement officials in the vicinity of the Library of Congress.
Court documents state that at around 9:45 a.m. on August 19, 2021, the U.S. Capitol Police and the FBI reacted to a bomb threat that was made by Roseberry. He was sitting in a black Chevrolet pick-up truck with no license plates, right next to the Jefferson Building of the Library of Congress.
Roseberry was observed gripping a cell phone, and he claimed that he was in possession of a detonator.
The suspect started a live stream via Facebook from inside the truck.
Roseberry expressed his discontent with the results of the 2020 election, calling for President Biden to step down. He then asked to communicate with the President directly to air his grievances.
The man claimed a toolbox in his truck held an ammonium nitrate and/or Tannerite bomb, stating that its explosive capabilities could damage as far as two and a half blocks of property. This large-scale destruction would impact the Library of Congress and other US-owned or rented properties.
He was observed in the Facebook videos grasping a metal keg with a putty material on the top. After being inspected by the FBI, the metal keg was determined to contain a tiny amount of smokeless black powder in the bottom. However, it was deemed to be unable to detonate.
Around 10:21 a.m., Roseberry started talking to the police by writing words on a small white board that he put in the driver’s window of the car.
For his dangerous threats, Judge Contreras has determined that the defendant could face up to 10 years of imprisonment.
