(NBC News) Military investigators continue to search for clues at Fort Hood and the apartment alleged gunman Ivan Lopez shared with his wife and young daughter before Wednesday's deadly attack that left four dead and 16 wounded.
Military officials say Army Specialist Lopez opened fire at one Fort Hood building, then drove to a second location, firing from his vehicle as he went, then entered a second building and fired more shots before taking his own life.
Lopez was evaluated just last month by an Army psychologist who told his superiors he showed no signs of violence to himself or to others.
