There was reportedly some confusion as the day began with a scheduled lockdown drill. "THIS IS A DRILL," an early morning memo notified Capitol staffers. "EXERCISE EXERCISE."The suspect has been identified as Larry Russell Dawson from Antioch, Tennessee, according to multiple media reports.
ABC News and NBC News report police have identified Larry Dawson of Antioch, Tennessee as the gunman who allegedly drew a [pellet] gun at the visitors center on Monday. U.S. Capitol Police would not confirm or deny it was Dawson, 66, at a press conference but said he was previously known to them. In October, Dawson was caught yelling he was a "Prophet of God" from the balcony of the House of Representatives.
On October 22, 2015, Dawson was arrested on charges of assault on a police officer and unlawful conduct at the Capitol, according to a police report obtained exclusively by The Daily Beast. Dawson also allegedly resisted arrest and ran from police, according to the report.
(According to MSNBC, Larry Russell Dawson died at the hospital on Monday evening. This appears to be a false report.)
