Death Toll at Naval Yard Shootings up to 12 (Updated)

One suspected shooter is dead; police seek two more

At least nine people are dead after as many as three shooters dressed in military style uniforms opened fire in a rampage at the Washington Navy Yard on Monday, police said, spreading fear and chaos across the region as authorities tried to contain the incident.

D.C. Police Chief Cathy Lanier said in a mid-day news conference that one of the suspected shooters is dead, while authorities are looking for two other suspects wearing green and tan military style clothing.

"The big concern for us right now is that we have potentially two other shooters that we have not located at this point," Lanier said.

Lanier described one as a white male wearing what appeared to be a khaki tan military uniform and a beret, and carrying a handgun. She said police also are looking for a black man, about 50, wearing an olive military-style uniform, and possessing a "long gun."

(Update: D.C. police said that at least 12 people are dead after as many as three shooters went on a rampage at the Washington Navy Yard on Monday. The U.S. Navy said shots were fired around 8:20 a.m. at the Naval Sea Systems Command Headquarters building, where about 3,000 people work.)
