WASHINGTON (CBSDC/AP) — President Barack Obama said that the nation is “confronting yet another mass shooting” after 13 people were killed, including the gunman, in Monday morning’s shooting at the Washington Navy Yard.
Officials say one gunman is dead, and one other suspect may be on the loose. Police say a man seen at the Navy Yard in a tan outfit has been identified and is not a suspect or person of interest.
At least 10 others were wounded in the shooting rampage.
“We will do everything in our power to make sure whoever carried out this cowardly act is held responsible,” Obama said.
The president said the victims were “courageous Americans” who knew about the risks of serving overseas.
“Today they faced the unimaginable violence they wouldn’t have expected here at home,” Obama said, adding that the shooting was a “tragedy.”
This was the second mass shooting to take place on a military installation since Obama has been in office. In 2009, Army Maj. Nidal Hasan killed 13 at the Fort Hood Army base in Texas.
According to data compiled by Mother Jones, the mass shooting at the Washington Navy Yard is the 20th mass shooting that has taken place since Obama took office in January 2009.
D.C. Mayor Vincent Gray said Monday afternoon that 13 are dead in shootings at Washington Navy Yard, including the gunman.
D.C. Police Chief Cathy Lanier said that the FBI will be taking over the investigation and that a motive is not yet known.
Federal law enforcement officials say the dead gunman has been identified as Aaron Alexis.
Alexis, 34, is from Fort Worth, Texas. He is believed to have a criminal record there and to be a holder of a concealed carry weapon permit. CBS News reports that Lewis, who was a former avionics electrician for the U.S. Navy, was also previously arrested in Seattle.
Witnesses described a gunman opening fire from the fourth floor, aiming down on people in the first-floor cafeteria. Others said a gunman fired at them in a third-floor hallway. It wasn’t clear whether the witnesses on different floors were describing the same gunman.
As witnesses emerged from the building, a helicopter hovered over it, schools were on lockdown and airplanes at nearby Reagan National Airport were briefly grounded so they wouldn’t interfere with law enforcement helicopters. Less than 2 miles away, security was beefed up at the Capitol, but officials said there was no known threat there. President Barack Obama was getting frequent briefings on the shooting.
About 3,000 people work at the Naval Sea Systems Command headquarters, which builds, buys and maintains the Navy’s ships and submarines and combat systems. A “shelter in place” issue has been ordered for the Navy yard’s personnel.
“I’m deeply shocked and saddened by the shooting this morning at the Navy Yard,” said Secretary of the Navy Ray Mabus in a statement. “Our thoughts and prayers are with the victims and their families. I have complete confidence in our first responders, and I continue to be completely focused on this very difficult situation.”
Todd Brundidge, an executive assistant with Navy Sea Systems Command, said he and other co-workers encountered a gunman in a long hallway of their building on the third floor. The gunman was wearing all blue, he said.
“He just turned and started firing,” Brundidge said.
Terrie Durham, an executive assistant with the same agency, said she also saw the gunman firing toward her and Brundidge.
“He aimed high and missed,” she said. “He said nothing. As soon as I realized he was shooting, we just said, ‘Get out of the building.'”
Rick Mason, a program management analyst who is a civilian with the U.S. Navy, said a gunman was shooting from a fourth floor overlook in the hallway outside his office. He said the gunman was aiming down at people in the building’s cafeteria. Mason said he could hear the shots but could not see a gunman.
Shortly after the gunfire, Mason said someone on an overhead speaker told workers to seek shelter and later to head for the gates at the complex.
Patricia Ward, a logistics management specialist, said she was in the cafeteria.
“It was three gunshots straight in a row — pop, pop, pop. Three seconds later, it was pop, pop, pop, pop, pop, so it was like about a total of seven gunshots, and we just started running,” Ward told reporters several blocks away from the Navy Yard.
Ward said security officers started directing people out of the building with guns drawn.
Police and federal agents from multiple law enforcement agencies responded. Ambulances were parked outside, streets in the area were closed and departures from Reagan National Airport were temporarily halted for security reasons.
Janis Orlowski, chief operating officer of Washington Hospital Center, told reporters the hospital was treating three gunshot victims in critical condition. One was Washington, D.C., metropolitan police officer and two were civilian women.
A U.S. Park Police helicopter hovered over the building and appeared to drop a basket with a person onto the roof.
District of Columbia schools officials said 12 public and charter schools and one administrative building in the vicinity of the Navy Yard were placed on lockdown. The action was taken out an abundance of caution, schools spokeswoman Melissa Salmanowitz said.
Naval Sea Systems Command is the largest of the Navy’s five system commands and accounts for a quarter of the Navy’s entire budget. Only security personnel were allowed to be armed on the campus.
The Navy Yard has three gates, according to its website. One is open 24 hours a day, seven days a week, and must be used by any visitors. A second gate is only for military and civilian Defense Department employees and the other is for bus traffic.
The Navy Yard is part of a fast-growing neighborhood on the banks of the Anacostia River in southeast Washington, just blocks from Nationals Park.
