Navy Yard Shooting: Investigators Search for a Motive

Only essential personnel will be allowed at the Washington, D.C., Navy Yard Tuesday as investigators try to figure out why a gunman killed 12 people and injured eight others inside the heavily secured building Monday morning. FBI and ATF agents searched a D.C. hotel where Alexis, who recently began work as a civilian contractor, was reportedly staying with five co-workers in town for business. News4’s Richard Jordan and Tony Tull have more on the search of a motive.
