A chaotic scene is playing out in Washington D.C., where a deadly mass shooting took place this morning at Navy Yard. At least 12 people have been reported dead and dozens more injured at the U.S. Naval Sea Systems Command Headquarters.
Authorities originally believed as many as three shooters opened fire. The prominent theory now, however, is that 34-year-old Aaron Alexis of Fort Worth acted alone. He died at the scene along with a dozen of his victims.
Alexis was working as a civilian contractor for the Navy and reportedly entered the building using another man's ID card, who is believed to be recently demoted or discharged. Authorities don't currently believe Alexis and the man whose ID he used worked in concert.
According to the a statement from the Navy, shots rang out around 8:20 am (Eastern time) and employees were told to shelter in place as emergency personnel worked to secure the area.
Reports on the mass shooting have been frantic and fraught with errors and concrete information about the attack is still scarce. No motive in the shooting has been identified.
