Joseph Bierbrodt, of Sheridan in La Salle County, pleaded guilty Friday to assaulting a police officer and civil disorder, court records show. Bierbrodt faced a variety of federal charges, including physical violence in a Capitol building or grounds, assault on a federal officer, obstruction of law enforcement and entering a restricted building, according to a criminal complaint filed in U.S. District Court in Washington.Bierbrodt's sentencing was set for Feb. 3, 2025. Joseph Bierbrodt and his brother, William, who is also charged in the complaint, were captured on security cameras breaching the U.S. Capitol through the Senate fire door, the complaint states. William Bierbrodt, who lives in Florida, had a “very large beard” and was seen on a mobility scooter, used a cane to break a window and reached inside to unlatch the door, letting other rioters inside.Joseph Bierbrodt wore a red hat, American flag face-covering and sunglasses. He rushed inside the building after his brother unlatched the door. The brothers and other rioters were met by U.S. Capitol Police, who attempted to stop them. That’s when Joseph Bierbrodt slammed an officer against a wall, the complaint states.In late October 2021, the FBI obtained images showing the brothers at the Capitol during the riot and used facial recognition technology to identify Joseph Bierbrodt. Another National Guard member also identified Joseph Bierbrodt for law enforcement, according to the complaint.Contributing: Emmanuel Camarillo
