Aaron Alexis was a contractor with security clearance.
Now we know how he got into the Navy Yard where he opened fire on more than a dozen people before he was killed. Dr. Drew and his guests will look at the seemingly contradictory statements from those who knew him. Was he an angry and withdrawn man? Was he a nice, intelligent person? Was he all of these things or none of them? His family says he suffered from PTSD after 9/11. A CNN source says he "heard voices".
If any of the disturbing accounts are true, how did this man pass a background check?
