At least 12 people are dead and others were wounded after a shooter opened fire 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 announced the mounting death toll in a 2 p.m. news conference. The suspected shooter is among the dozen dead.
But hours after the rampage began, it was still unclear whether the shooting was the act of a lone gunman, or if other shooters were involved. Lanier initially said authorities were looking for two other potential shooters dressed in military style clothing. But shortly after she announced a detailed description of two suspects, city officials said one had been located and cleared.

Mayor Vincent C. Gray said no motive is known. He said they have no reason to believe it was an act of terrorism, though he said he could not rule it out.
Lanier described the other possible suspect, who has not been located, as a black man in his 40s with gray sideburns, wearing an olive-drab military-style uniform.
