WASHINGTON (Reuters) - Thousands of workers streamed back into the Washington Navy Yard on Thursday, three days after a former reservist working at the site as a contractor opened fire with a shotgun on a cafeteria full of workers eating breakfast, killing 12 people.
The sprawling, walled complex, which covers about 16 blocks of the U.S. capital, had been closed to all but essential personnel and those involved in the investigation into why 34-year-old Aaron Alexis, who died in a gun battle with police, mounted his attack.
