Authorities say the former Navy reservist, who had been living in Fort Worth, was the dead gunman at the Washington Navy Yard.
Aaron Alexis, 34, has been identified by officials as the gunman in Monday’s shooting at the Washington Navy Yard. In 2010, Alexis was arrested by Fort Worth police after a bullet was fired through the floor of his upstairs neighbor’s apartment. He told police that his gun accidentally discharged while he was cleaning it, and no charges were pursued. Fort Worth Police Department/via AFP/Getty Images Buy Photo
