The United States Department of Homeland Security canine teams are at the scene of the Naval yard mass shooting in Washington, D.C. on Monday morning. There are multiple injured victims and 12 deaths have now been confirmed, including one of the shooters.
Federal, state and local police SWAT teams and K-9 units are looking for two other potential gunmen, wearing military-style uniforms, including one wearing a beret. The D.C. Police Chief confirmed during a press briefing that one gunman is dead, and one or two more gunmen remain at large.
The U.S. Department of Homeland Security's Federal Protective Service (FPS) Explosive Detector Dog (EDD) teams are trained to conduct searches for a variety of explosive materials near building exteriors, vehicles, packages, and people in and around federal facilities.
Initial reports indicated that one shooter opened fire at the Navy Sea System Command Headquarters in Washington, D.C.. However, law enforcement officials now say one or two additional gunmen may be responsible for several injured victims and "multiple fatalities."
During a press briefing, D.C. Metropolitan Police Chief, Cathy Lanier confirmed that one suspect is dead and potentially one or two other gunmen, in olive colored military uniforms were involved.
D.C. Police Chief Lanier stated that one of the men police were looking for was a "white male in military fatigues".
"He was last seen around 8.35 a.m. this morning with a handgun," she said.
President Obama has been briefed several times about the Navy Yard shooting by his homeland security adviser, Lisa Monaco.
U.S. Capitol Police have stepped up security at the Capitol, and several schools in the area have been placed on lockdown. Additionally, enhanced security is in place at the Pentagon, out of the abundance of caution.
In a statement released by the U.S. Department of Defense, Pentagon Secretary George Little said:
"This is a fluid situation. Navy officials are working closely with law enforcement and emergency management representatives from the FBI and the District of Columbia to secure the scene and begin the investigation. More information will be released from the appropriate agency as it becomes available."
The FBI is now the lead agency in the Navy yard shooting investigation. After the 9/11 terrorist attacks, the U.S. Department of Homeland Security designated the FBI as the lead agency in all cases in which acts of terrorism are suspected.
Witnesses to the mass shooting at the Navy yard, who made it out safely are skeptical of police reports that more shooters remain at large.
