D.C. Mayor Vincent Gray said during a 4 p.m. news briefing at least 13 people are dead - including one alleged shooter - in the wake of a shooting spree Monday morning at the Washington Naval Yard in the southeast corner of the city. He also said one of two potential additional suspects had been cleared from the case.

"Earlier today we talked about the possibility of there being two other suspects, one of those has been ruled out; that gentleman has been identified and is no longer a suspect," Gray said. "He's been talked to by law enforcement officials and there's no reason to continue any views that he may have been involved in this." 

But law enforcement officials are still looking for another man, identified as wearing a drab olive uniform, around 50 years of age, approximately 5'10" and African-American. 

 

"We don't know what the motive is at this stage¬but we don't have any reason at this stage to suspect terrorism," Gray said.

Valerie Parlave, assistant director in charge of the Washington field office of the FBI, also confirmed the identity of the deceased alleged shooter. 

"We can confirm that the deceased shooter from this morning has been identified at 34-year-old Aaron Alexis of Fort Worth, Texas," she said. News reports have described him as a defense contractor who may have entered the secure building with someone else's identification card.

At least 12 people are dead and eight people are injured as a result of the D.C. Navy Yard shooting spree Monday, according to local authorities. 

D.C. Mayor Vincent Gray also confirmed during an afternoon news briefing that law enforcement is still investigating whether or not there was more than one shooter. 

"Right now we are confirming at least 12 fatalities, we had a few additional folks who were injured, they were not fatally injured," said D.C. Police Chief Cathy Lanier, adding that several law enforcement officials are among the injured. 

"A large part of the area is still on lockdown, we are asking the residents to stay out of the area and remain in your home," Lanier said. "We do feel like the area is safe, but we do still have an active search for potentially additional suspects."

The investigation has been handed over to the FBI and teams of investigators from multiple agencies are continuing to search the Navy Yard complex, a process that could take a couple more hours to complete, Lanier said. 

"We have no indication of any motive at this time," she said. "At this point I think the actions of the police officers without question helped to reduce the number of lives lost."

Police continue to be on the lookout for two potential suspects. 

"The first is for a white male between 40 and 50 years of age, wearing a tan, what appears to be military uniform consistent with a naval uniform and a beret-style hat," Lanier said. "We also have a lookout for a black male, between the ages of 40 and 50 and an olive, military-style uniform. He is approximately 5'10" and 180 pounds or medium complexion and graying sideburns." 

Gray said the next briefing is scheduled for 4 p.m.
