Killeen, Texas (CNN) - A day after a shooting rampage at Fort Hood, Texas, left three soldiers dead and 16 wounded, a profile emerged Thursday of the killer as an experienced soldier who was grappling with mental illness, but no answers were forthcoming as to a possible motive.
The incident began Wednesday at about 4 p.m., when Spc. Ivan Lopez, 34, went from one building at the sprawling Texas military base to a second, firing his .45-caliber handgun.
