Washington, D.C. Police chief Cathy Lanier said that two of the shooters have not been located. She confirmed that one of the shooters in the rampage has been killed, but a white male wearing khaki military-style clothes and a beret is still being searched for by the police. He was seen carrying a handgun. Another person they are looking for is a black man who is approximately 50 years old, wearing a military-style olive, drab uniform – who may be carrying a rifle. Though dressed in military apparel, Lanier said they may very well not be members of the United States military.
Residents in the area have been asked to stay out of the area and in their homes as the search and investigation are still very active.
Vincent Gray, the mayor of Washington, said that it is believed to be an isolated incident with no other military installations appearing to be in involved with – what he has called – a horrific tragedy.
President Barack Obama commented by praising the victims as patriots who know the dangers of serving abroad, but who were now subjected to unimaginable violence that they wouldn’t have expected at home. Obama promised that federal and local law enforcement officials will collaborate in investigating the shooting rampage.
The incident began at 8:15 a.m. ET at the Naval Sea Systems Command headquarters located along Washington’s Anacostia River. It began on the fourth floor and then moved to the building’s open atrium area.
Due to the incident, officials have stepped up security in all federal buildings in the area. Air traffic at Reagan National Airport was briefly grounded, and schools in the area were placed on lockdown.
At this point, it is known that a Washington D.C. policeman and a Naval Base security officer are among the dozen victims.
Some-3,000 people work at the Naval facility. As of 12 p.m., lockdown at the facility was still in effect while authorities continue to search for others involved in the shooting.
UPDATE: (6:00 p.m. CT) More information regarding the shooter has been revealed by the Los Angeles Times which says that Aaron Alexis - the man who shot and killed 12 persons in a horrific event that injured at least a dozen others - was discharged from the service in 2011 after several disciplinary infractions. He served in the Navy from 2007 until 2011 as an aviation electrician's mate 3rd class. ABC - via WLS radio in Chicago - has reported that Alexis had an incident involving a gun in 2010 which allegedly did not foreshadow an incident as occurred today. Media has now learned that Alexis went to the huge Building 197 - the headquarters of the Navy Seal Systems Command after passing the entry gate with an ID was not issued to him. He was armed with three weapons which included an assault rifle and went to the fourth floor of the building. At approximately 8:15 a.m. on Monday, he started shooting down to the atrium which is where the employee cafeteria is located. It was crowded at the time. It took two hours of exchanged gunfire with Navy security and Washington, D.C. Police before the gunman was killed.
Additionally, CBS is reporting that Aaron Alexis had two incidents involving guns in the past. One was in Forth Worth, Texas, where he shot a ceiling and floor, allegedly because he was cleaning his registered gun with slippery hands and it went off. However, a terrified female who lived above him in an apartment complex said she was terrified of him because he confronted her about making too much noise - which she says she wasn't causing - and he intimidated her. No charges were filed in that incident. However, he was charged for malicious mischief twice: once in Seattle, and once in Forth Worth in 2010 for discharging a firearm in public. The CBS report also indicates that Alexis was enrolled at the Great Lakes Naval Training Center in North Chicago, Illinois from May of 2007 until July of that year. He also served in Forth Worth from February of 2008 until January of 2011. He received the Global War on Terrorism Service Medal and the National Defense Service Medal. He reportedly owned a handgun and a concealed gun license.
UPDATE: (3:12 p.m. CT) Washington, D.C. Police have said that they are no longer looking for a second gunman in the shooting rampage which indicates that there was no second shooter and Aaron Alexis acted alone.
UPDATE: (2:35 p.m. CT) Huffington Post is reporting that Aaron Alexis, 34, originally from Forth Worth, Texas, is the name of the suspect killed in the Navy yard shootings. He entered the facility with an ID that wasn't his. It is not known if the ID was stolen or that of an accomplice.
UPDATE: (1:55 p.m. CT) NBC News is reporting that the white male is no longer a suspect as he has been cleared by Washington, D.C. police. The news source has also said the shooter - who died in the flurry of gun activity with police approximately 2 hours after the initial gunshots werer fired - was a civilian contractor with the Navy - a 34-year-old man from Texas.
