WASHINGTON, D.C. -- In the Washington Navy Yard Shooting, the FBI has confirmed there was only one gunman, Aaron Alexis.
The 34-year-old had the proper security pass to get on the base.
The fact that Aaron Alexis was cleared onto the base Monday, apparently concealing his shotgun, is promping hard questions about how he was able to keep his secret level security clearance.
Alexis has been suffereing from a host of serious mental issues, including paranoia, a sleep disorder, and hearing voices. Alexis has been treated for thise conditions since August by the VA for Mental Problems.
Senator Dick Durbin says Alexis shouldn't have had a security clearance or an ability to own a gun.
"But we have to do everything to keep guns out of the hands of those who would misuse them. Felons who have a history of misusing firearms. The mentally unstable who can't be trusted to have a firearm," Durbin said.
Officers now say Aaron Alexis entered the Navy Yard armed with only a shot gun he recently purchased legally in Virginia.
