Suspect in Capitol attack that left officer dead suffered delusions and paranoia, source says Author: Michael Balsamo, Eric Tucker, Nomaan Merchant, Associated Press Updated: 4 hours ago Published 4 hours ago Share on Facebook Print article WASHINGTON — The man who rammed a car into two officers at a barricade outside the U.S. Capitol, killing one of them before he was shot to death by police, had been suffering from delusions, paranoia and suicidal thoughts, a U.S. official told The Associated Press on Saturday. Investigators believe it was an isolated incident from a disturbed young man. Video of the Friday afternoon attack shows the driver emerging from the crashed car with a knife in his hand and starting to run at the pair of officers, Capitol Police acting Chief Yogananda Pittman told reporters. Police shot the suspect, 25-year-old Noah Green, who died at a hospital.
