New details were learned Thursday afternoon concerning the latest shooting at Fort Hood. Fort Hood commander, Lt. General Mark Milley and U.S. Senator John Cornyn addressed the media at a press conference.

The soldier at the center of Wednesday's shooting has been identified as Army Specialist Ivan Lopez.

Spc. Lopez turned his gun on himself after killing three people and wounding 16 others Wednesday at the nation's largest Army post. It's the same Texas military base where more than a dozen people were fatally shot by a soldier in 2009.

During Thursday's press conference, Gen. Milley said Lopez's psychological issues may be the "fundamental, underlying cause" of the attack.

Lopez had been undergoing treatment for depression and anxiety while being evaluated for post-traumatic stress disorder at Fort Hood.

Milley also says Lopez was likely involved in an argument before the shooting, but there is "no indication he was targeting specific people."
