Aaron Alexis (pictured right), opened fire 
and killed 12 people tyesterday Monday September 16th at the Washington Naval Yard in Washington DC before being 
shot and killed by responding officers. The 34-year-old 
who worked as a civilian I.T contractor at the military base, entered the complex's cafeteria around 8.30am brandishing 
an AR-15 semi-automatic rifle, shotgun and handgun and began shooting.
 It is thought that he used another 
employee of the base's identification card to gain entry to the heavily 
secured Building 197, where he carried out his deadly attack. Aaron killed 12 people and injured at least 15, who are all in critical conditions.
Aaron, from Fort Worth Texas, served in 
the U.S. Navy for almost four years before being kicked out in January 
2011 for 'misconduct'. The motive for the killing has not been revealed 
though there are speculations that it could be connected to his 
dismissal from the U.S. Navy. RIP to those who lost their lives. Read
