WASHINGTON DC. - At least 12 people were shot and killed at the Washington Navy Yard on Monday morning, Washington officials said. The suspected gunman, 34-year-old Aaron Alexis, also died in the incident at the Naval Sea Systems Command building, reports CBS News.
A law enforcement official told CBS News' Pat Milton the suspected shooter apparently had a handgun, an AR-15 assault rifle, and a shotgun with him and was wearing dark blue clothing.
"We are confronting yet another mass shooting," President Obama said today during remarks that were intended to address the financial crisis. "And today it happened on a military installation in our nation's capital."
While Alexis' motive is still not clear, officials said he is a former avionics electrician with the U.S. Navy. He had been arrested at least twice previously: once in Seattle for malicious mischief, and once in Fort Worth in 2010 for discharging a firearm in public. He has lived in New York City also.
Police and emergency crews gathered outside the Naval Sea Systems Command Headquarters building, where the shooting was reported at 8:26am ET. 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. It builds, buys and maintains the Navy's ships and submarines and their combat systems.
