An Iraq war veteran at Fort Hood who killed four people and wounded 16 others at the post on Apr. 2, before taking his own life was being evaluated for post-traumatic stress disorder, according to military officials.
According to reports, the suspect Ivan Lopez was an active-duty enlisted soldier who served four months in Iraq.
Officials said he was being treated for depression, anxiety and other behavior and mental issues but had not yet been officially diagnosed with PTSD.
Lopez had also been examined by a psychiatrist within the last month, but showed no signs that he might commit a violent act. He was prescribed Ambien, a sleep aid, and other medications to treat depression and anxiety.
On Apr. 2, Lopez walked into a building that afternoon and began firing a .45-calibre semi-automatic pistol,according to reports.
Out of the 16 that were wounded, nine remain in hospital.
