Aaron Alexis has been identified by police as the dead Washington Navy Yard shooter, NBC News reports.
Alexis, 34, originally of Fort Worth, Texas, recently began working at the Navy yard as a civilian contractor, the station reported. The FBI confirmed his identity in the afternoon.
Alexis was armed with an assault rifle and a handgun, two law enforcement officials tell the Washington Post. One of the sources said he also had a shotgun. All the weapons have reportedly been accounted for. His aunt, Helen Weeks, told the paper that he grew up in Brooklyn, N.Y. with his mother, Sarah, and father, Anthony.
At least 13 people were killed -- including Alexis -- and more were wounded at the Naval Sea Systems Command Headquarters building after at least one gunman opened fire after 8:20 a.m. Monday, a Defense Department official said.
Metropolitan Police Chief Cathy Lanier said at an earlier press conference that a Metropolitan Police officer is among those who have been shot, among other "multiple victims inside who are deceased." There were other reports that a naval security guard was reportedly among the wounded.
At a press conference Monday night, Navy Vice Admiral Bill French said that all of the casualties were civilians, according to NBC Washington.
The suspect was reportedly killed at the scene, but few details about the death were immediately available. One other person of interest is still on the loose. He's described as a black male, 50, with an olive military-style uniform who may be in possession of a long gun.
A third person of interest was cleared.
UPDATE: At a 10 p.m. Eastern press conference on Monday, Police Chief Cathy Lanier said that law enforcement has "the single and sole person responsible" for the shooting in custody, dispelling rumors that a second suspect is still at large.
The FBI released a photo and description of Alexis, asking the public for any information about the deceased suspect:

Alexis Was 'Determined To Kill As Many People As Possible'
WASHINGTON -- Alleged Navy Yard shooter Aaron Alexis acted alone and was "determined to kill as many people as possible," law enforcement officials said Tuesday.
Officials would not comment on Alexis' alleged motive during a press conference held Tuesday afternoon outside the FBI's Washington Field Office, but said they had determined he arrived in the area around Aug. 25 and had been staying at the Residence Inn in Southwest Washington, D.C. since Sept. 7.
The FBI is investigating "hundreds" of tips they have received Monday's shooting. "No piece of information is too small," said FBI Assistant Director in Charge Valerie Parlave, asking for additional assistance from the public.
Metropolitan Police Officer Scott Williams is doing well and is expected to make a full recovery, according to MPD Chief Cathy Lanier. "We have a very good prognosis from the doctors, he does have serious injuries to his legs. Again, I know the officer and I know his personality, and I'm real confident he will not only walk again but probably will outrun most of us again," Lanier said.

Aaron Alexis Got Honorable Discharge Despite Disorderly Conduct, Insubordination
Alexis was honorably discharged from the Navy in 2011 after bouts of insubordination, disorderly conduct and being absent from work without authorization.
The AP reports:
Officials said the bad conduct was enough to make it clear Alexis would not be a good sailor, but not enough to warrant a general or less-than-honorable discharge. They also did not involve criminal offenses, so did not trigger any court-martial proceedings.
