Navy Yard Shooter Had History Of Mental Illness Treatment


UPDATED: Tuesday September 17, 2013 6:17 PM

The streets around the Washington Navy Yard, the scene of Monday's shootings that left a gunman and 12 others dead, reopened on Tuesday.
    
Access to the Navy Yard is being limited to mission-essential personnel.
   
In addition to the 12 who died, eight others were wounded. All of them are expected to survive.
    
Authorities continue to learn more about the gunman -- a defense contract employee and former Navy reservist who used a valid pass to get onto the installation and started firing inside a building. He was eventually killed in a gun battle with police.
    
Law enforcement officials say Aaron Alexis had been suffering from a host of serious mental issues, including paranoia and a sleep disorder. They say he had also been hearing voices in his head.

They say he'd been treated since August by the Veterans Administration for his mental problems. But the Navy hadn't declared him mentally unfit, which would have rescinded a security clearance he had from his earlier time in the Navy Reserves.

The gunman had at least two past run-ins with police over shooting incidents. Seattle police say they arrested Aaron Alexis in 2004 for shooting out the tires of another man's vehicle. Alexis later told detectives he'd had an anger-fueled "blackout." The other incident occurred in Texas in 2010.
