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.
