The nation's capital went into lock down Monday morning when a former Navy reservist killed 12 people in a shooting rampage at the Washington Navy Yard. Several more were injured.
The shooter, who has been identified as 34-year-old Aaron Alexis, was discharged by the Navy in 2011 for what an official described as a "pattern of misconduct." Alexis was armed with an AR-15 assault rifle, a shotgun and a handgun.
In the chaos of the shooting, which began shortly after 8:00 AM, two other gunmen were initially suspected. After Alexis was killed by law enforcement, it was determined that he acted alone.
The mass shooting is marked as the worst loss of life in a single incident in the D.C. area since the September 11, 2001 attack on the Pentagon that killed 184 people.
