Gunman, 12 others dead in attack at D.C. Navy yard

City goes into lockdown

WASHINGTON — A worker for a defense contractor shot to death at least a dozen people as the workday began at the Washington Navy Yard on Monday, creating an improbable morning of horror at a military facility with armed guards at every gate and leaving investigators seeking clues about what spurred the attack.

The suspected gunman, identified by the FBI as Aaron Alexis, 34, of Fort Worth, was a former Navy reservist who reportedly had previous run-ins with police over firearms. Police said Alexis, who used a valid badge to enter the complex, was killed in a fierce gunbattle with officers.
