The white male in the tan outfit has been identified and is not a suspect or person of interest
D.C. Mayor Vincent Gray said at least 12 people were killed in the Navy Yard rampage as D.C. Police Chief Cathy Lanier revealed one shooter was killed at the scene and authorities are looking for another man — after a third was cleared of involvement in the attack.
NBC first identified the slain gunman as Aaron Alexis, a 34-year-old man from Texas. He was a civilian contractor who reportedly stole a military ID to gain access to the Navy Yard.
A senior federal law enforcement official said authorities were investigating whether the main shooter was motivated by a dispute with employees at the Navy Yard.
Authorities were still clearing the building early Monday afternoon.
The two at large suspects were dressed in military garb but are not believed to be U.S. service personnel, Lanier said.
One was a young white man in a khaki like uniform and the other was a black man in his 50s with a long rifle in an olive colored garb, she said.
UPDATE: The D.C. Police Department tweeted the white male in the tan outfit has been identified and is not a suspect or person of interest.
Earlier, Navy Capt. Ed Buclatin said all the injuries occurred in Building 197 of the Navy Yard, which is home to the Naval Sea Systems Command.
Navy officials had reported shots were fired at 8:20 a.m. at the headquarters of the Naval Sea Systems Command in Southeast Washington.
D.C. police quickly deployed an “active shooter team” within seven minutes of reports of shots fired, Ms. Lanier said.
Two of the shooting victims are D.C. police officers.
Omar Grant, a civilian worker at the Navy Yard said he was on the first floor of the five-story atrium when he heard the first shot. “At first I didn’t know if someone dropped something,” Mr Grant said. “It echoes in an atrium.”
Then he heard the other shots, Mr. Grant said.
“It was unmistakable,” he said. “Nobody had dropped anything. Those were shots.”
The Navy has issued a shelter-in-place order for personnel, Pentagon Press Secretary George Little said.
“We believe there has been loss of life and several injuries,” Little said. “We continue to monitor this ongoing situation.”
George Washington University Hospital has confirmed that a 60-year-old male was killed in the Navy Yard shooting Monday morning.
A spokesman said the man, whose name was not given, was dead on arrival to the hospital at around 9 a.m, about 40 minutes after the shooting.
The spokesman said the man was shot in the left temple and the wound was “not survivable by any stretch.”
The hospital said it was told to be prepared to take more victims of the shooting.
A spokeswoman for Medstar Washington Hospital Center said the D.C. hospital has already received three people wounded in Monday’s shooting at the Navy Yard and “we’ve been told to expect more.”
Chief Medical Officer Janis Orlowski said one D.C. police officer was already in surgery. The three shooting victims — one man and two women — have “a good chance of survival.” One of the women had been shot in the hand and head, she said.
Ms. Orlowski told reporters she did not know if any other victims of the shooting would be transported to the hospital. She said Medstar officials have been in touch with other hospitals in the area to coordinate treatment of victims.
The rampage plunged D.C. into chaos during the morning commute.
The 11th Street Bridge was shut down, and people were routed away from the area, the police spokesman said.
Flights departing from Ronald Reagan Washington National Airport were stopped, the FAA said, and incoming flights are being held at their origin. Flights resumed shortly after 11 a.m.
At the Capitol, the Senate came into session as scheduled at 2 p.m. but then adjourned, postponing all business until later in the week.
“In light of the events at the Navy Yard area today, we’ve decided to recess the Senate until tomorrow morning,” Senate Majority Leader Harry Reid said.
At least nine D.C. public schools in the area went into lockdown.
