An armed police office standards guard over the Washington Navy Yard after deadly shooting
34-year-old Navy Yard gunman Aaron Alexis was a schizophrenic man who shot and killed 12 people this week in Washington, D.C. and wounded others, before being shot and killed by police. The 12 people he killed were between the ages of 50-73. It is the second deadliest military base shooting, behind Fort Hood. Investigations into the incident reveal Alexis was mentally ill. He was officially diagnosed as schizophrenic, receiving treatment through the Navy.
However, Alexis was able to purchase a 12-guage shot gun and ammunition for $540, in spite of background checks (much like the Virginia Tech mass shooting). Alexis also had a history of violence, regarding incidents that involved guns. What is even stranger is Alexis, with his mental history, has security clearance which granted him access to classified documents at the Department of Defense.
