Lone suspect in Navy yard rampage had history of gun arrests

Sept. 17 (Bloomberg) -- The shooting rampage at the Washington Navy Yard was the work of a lone gunman, a government contractor named Aaron Alexis, who entered the facility legally with a valid identification card, according to authorities.
Even as those details came into focus, Washington’s mayor and police chief still couldn’t say why Alexis went to the base where he worked, about a mile from the U.S. Capitol, and opened fire, killing 12 people, before he was shot to death by police.
Washington Mayor Vincent Gray said officials see no sign of terrorism, though he offered no other clues to Alexis’s motive. Police Chief Cathy Lanier said officials ruled out the possibility that Alexis had accomplices, after starting the day saying there might have been as many as two other gunmen.
“We now feel comfortable we have the single and sole person responsible for the loss of the life inside the base today,” Lanier told reporters at a briefing last night.
