At least 12 people are dead after a horrific shooting spree this morning at the Washington Navy Yard in Washington, D.C.
Initial reports described a "lone gunman" in an active-shooter scenario, but the latest update from authorities describes one dead shooter and two potential additional shooters on the loose.
"We have one shooter deceased," said D.C. Metropolitan Police Chief Cathy Lanier at a live press conference held just after noon Eastern time, and "potentially two other shooters" on the loose.
The two at-large suspects are described as a white male in his 40s-50s, in a khaki Navy-style uniform, wearing a beret and carrying a handgun; and a black male in his 50s in a military-style olive-colored uniform, with gray sideburns, carrying a long gun.
Hospitals treating the victims have reportedly discovered at least two types of bullets — which indicates multiple weapons were used. This does not verify multiple gunmen, as one shooter could be armed with multiple weapons.
An AR15 a shotgun and a handgun were all found on the shooter, according to NBC4

In retracted statements, a man was named as the deceased gunman by CBS' Charlie Kaye on Twitter. Those tweets were quickly discredited, and the reporting was based on a military ID found at the scene.

The yard is on lockdown. Flights were grounded at Reagan Airport. All D.C. schools were on lockdown.
There was a massive police and emergency response, and the scene was chaotic, to say the least — cops speeding to reach the scene, people running in various directions, helicopters circling.
