WASHINGTON - Washington, DC police say 13 people are dead in an attack at the Naval Sea Systems Command Headquarters, where 3,000 people work. Suspected shooter Aaron Alexis is among those killed. This blog follows the events as they unfolded Monday.

10:10 pm

Press conference with DC Mayor Vincent Gray, DC Police Chief Cathy Lanier and Valerie Parlave, FBI Assistant Director of the Washington Field Office:

BREAKING: DC Police lifts shelter-in-place; has single and sole shooter, deceased suspect Aaron Alexis.

: We have exhausted all means available to eliminate that possible last suspect [who was previously believed to be at large]. We are comfortable to lift shelter-in-place in the area. We feel we have single and sole person responsible for shooting.

Witness interviews and some camera views suggested there was potential that another shooter was involved. We believed best action to take was to make sure community was safe, first. We have spent last several hours trying to go through everything possible until we were 100 percent comfortable we cleared that information.

Parlave: Suspected shooter Aaron Alexis had legitimate access to Navy Yard as a result of his work as a contractor. He utilized a valid pass to gain entry to the Navy Yard. 

FBI expected to spend another 48 hours at the Navy Yard. Most people alive have been cleared from the scene. 

Gray: Eight people incurred injuries. Of the eight, three were shot, including a Metropolitan police officer. Two other civilians suffered minor injuries. The other five injuries range from stress reactions, like chest pain, to contusions from falling. There's no reason to think they won't be fine.

We anticipate traffic patterns will be back to normal on Tuesday morning, and bridges will be open.

We've been in close contact with White House. The president has reached out through his staff to connect with us as this process unfolded throughout the day. 

8:25 pm Vice Admiral William French confirms 27 Navy Yard casualties: 13 dead, including shooter, and 14 injured. All 12 victims killed were civilians.

French says approximately 2,000 employees remain on site at naval installation, awaiting FBI interviews. Evacuation will take a few hours.

6:30 pm Police arrest a man outside the White House after he threw lit firecrackers over a fence at the presidential compound. Officials have not stated a motive or drawn a connection to the Navy Yard shooting, but the incident put an already tense Washington on even further edge after Monday's deadly rampage.

6:12 pm Press conference with DC Mayor Vincent Gray, DC Police Chief Cathy Lanier, FBI Assistant Director of the Washington Field Office Valerie Parlave, and DC Congresswoman Eleanor Holmes Norton:

Gray: We're still seeking the identity of the person identified as having a drab olive-colored uniform, a man about 50 years old.

I want to extend on behalf of the entire city our heartfelt condolences to the families of those who were killed in this horrific tragedy.

Family and friends wait to greet staff of the Navy
Family and friends wait to greet staff of the Navy Yard as they are bused to Nationals Park, in Washington, Sept. 16, 2013.
There were 13 tragedies, 12 of which occurred at the site, including the shooter, and one at the hospital.
No known motive at this juncture. There is no information to suggest it was terrorism at this point.
We will continue through the night with this investigation, and obviously in the days and weeks ahead.
Lanier: We are still continuing to ask our community to remain out of the area and shelter in place. We still are working diligently to verify or clear whether we have the last person of interest.
This is still an active investigation. We still have a lot of law enforcement in the area. Please stay out of the area until we give the all-clear.
Our officer from the Metropolitan Police Department is out of surgery and is stable. He's going to be okay.
Traffic closures across M Street will continue throughout the night. 
Parlave: No further details at this time about the deceased shooter, Aaron Alexis. Public is encouraged to look at photo of the shooter and share tips to 1-800-CALL-FBI.
This image released by the FBI shows a photo of Aa
This image released by the FBI shows a photo of Aaron Alexis, who police say was the gunman killed at the Navy Yard shooting, Sept. 16, 2013.
No piece of information is too small as authorities try to piece together the recent movements and contacts of the suspect.
Lanier: There is misinformation getting out through a variety of sources. To the media, if you have sources inside law enforcement agencies, they are not confirmed unless they're coming through the official body or through the FBI.
If you have sources reporting something, try to verify before you put it out. Misinformation results in additional calls that divert resources.
Holmes Norton: The fear rises when people don't have information and don't feel safe. This is a thriving community of residents. It's not a place just for large federal facilities. 
To residents coming home today, the response of the police, taking down the shooter so quickly, reminds me again that this is the safest city in the United States. Not safe from attack, but safe.
?The police and responders saved many lives. When this investigation is over, we'll have a sense of just how many. 
Tonight, we want to say to residents, we don't think there's anything to fear in this city. 

5:45 pm

President Obama orders United States flags to be flown at half-staff until sundown Friday to honor the victims of the Navy Yard shooting:

"As a mark of respect for the victims of the senseless acts of violence perpetrated on September 16, 2013, at the Washington Navy Yard, by the authority vested in me as President of the United States by the Constitution and the laws of the United States of America, I hereby order that the flag of the United States shall be flown at half-staff at the White House and upon all public buildings and grounds, at all military posts and naval stations, and on all naval vessels of the Federal Government in the District of Columbia and throughout the United States and its Territories and possessions until sunset, September 20, 2013.

This evening's Washington Nationals baseball game, blocks from shooting, postponed until Tuesday afternoon.

Lanier: This is one of the worst things we've seen. Officers moving through the building found multiple victims, with gunfire still going on.  

There is no question suspect would have kept shooting [if he was not engaged by police].

Second individual is in good spirits, ordering doctors and nurses around, and they jokingly told her they were in charge. She is in surgery and is expected to have full recovery.

Third individual is not in surgery. She is a "very lucky lady." She suffered a significant wound to her head but it did not puncture her skull. She will recover without surgery. She's in very good spirits.

We are confronting yet another mass shooting, and today it happened on a military installation in our nation's capital.

It's a shooting that targeted military and cilvilian personnel. These were men and women going to work, doing their job. They were protecting all of us. They were patriots and they know the dangers of serving abroad ... but today they faced the unimaginable violence that they wouldn't have expected here at home.

I want the investigation to be seamless so that federal and local authorities are working together and as this investigation moves forward we will do everything we can to make sure whoever carried out this cowardly act is held responsible.

We stand with the families of those who have been harmed. They're going to need our love and support.
