Suspected U.S. shooter worked as civilian IT contractor for Navy

WASHINGTON (Reuters) - Aaron Alexis, the 34-year-old suspected shooter behind Monday's rampage at the U.S. Navy Yard in Washington, was at some point a civilian contractor for the U.S. Navy in the information technology area, Navy Secretary Ray Mabus said. Alexis' ties to the Navy could help determine his motive and how he had access to the Navy Yard. "At one point, he was a Navy contractor. Whether he was today, I don't know," Mabus told CNN.
