The gunman who killed three soldiers and injured 16 others in a shooting rampage Wednesday at Fort Hood, Texas, acted alone, Army officials revealed Friday in a press conference.
Investigators have found no evidence to contradict this scenario, but they are also not ruling anything out at this early stage, according to Chris Grey, spokesman for the U.S. Army Criminal Investigation Command.
Grey said the probe into the shooting has so far uncovered no evidence that the alleged shooter, Spc. Ivan Lopez, had any links to terrorism.
Investigators are also digging into Lopez's combat experience in Iraq, but have so far not discovered any specific traumatic events that he may have been exposed to.
"We may never know exactly why the alleged shooter did what he did,” Grey told reporters.
Army officials also said they don't believe Lopez's underlying medical conditions directly led to Wednesday's deadly events, according to Lt. Gen. Mark Milley, the post’s commanding general.
Lopez was being treated for anxiety and depression and evaluated for post-traumatic stress disorder.
