She said one shooter involved in the situation is dead following the shooting.
Lanier said that one of the shooters was a white male seen at around 8:40 a.m. this morning with a khaki tan military uniform and a beret. He was last seen with a handgun, she said.
Lanier added that police are also looking out for a black man, approximately 50 years old, who may have been in possession of a “long gun.” That man was wearing an olive military-style uniform.

A dispatch from Al Jazeera America DC reporter Naureen Khan:
Air Force Tech Sergeant David Reyes waited for his wife, who works for human resources at the Navy in the building next to Naval Sea Systems Command and was still on lockdown Monday afternoon, outside Navy Yard.
Reyes said she had texted him that morning to tell him all employees were told to stay where they were as the situation unfolded. Law enforcement officials continued to search rooms one by one to clear them before anyone could be released. Reyes spent the morning feeding her news before making his way to the scene to see what he could find out.
"I just want to get her out of there but the best thing for them right now is just to stay put."
Reyes said he wasn't particularly surprised that a shooter had managed to penetrate such s secure facility.
"Honestly, it can happen anywhere," he said. "You just hope and pray people aren't that demented."

A dispatch by Al Jazeera America DC reporter Naureen Kahn:
Carlos Perez and Carole Tracy came to DC from Poquoson, Virginia for the Nationals game against the Braves Monday night and were staying at the Courtyard Marriott down the street from Navy Yard. They were awoken by the sound of sirens and say they saw police administering CPR to a man laying on the ground on M Street and New Jersey from their 14th floor hotel room. Shortly thereafter, mayhem broke loose as they saw law enforcement officials flood the scene.
"There were hundreds of them racing down the street cordoning off the area," Tracy said. "It was like a battleground."
The Nationals stadium is now being used as a holding area for families awaiting word from employees still inside the command facility.
