According to CNN:
One suspect is dead after a shooting at the Washington Navy Yard, but two others may be on the loose, the D.C. police chief said Monday.
“The big concern for us right now is that we potentially have two other shooters that we have not located at this point,” Washington Police Chief Cathy Lanier told reporters.
Multiple people were killed in the shooting rampage, Lanier said, which sent police in SWAT team gear swarming to the scene Monday morning.
Hours later, Lanier said authorities were still looking for a white man and a black man in military-style clothing who could be connected to the shooting.
“We have no information to believe that either of those folks are military personnel, but we do have information that those individuals are wearing military-style uniforms,” she said.
