Four Dead, 16 Injured in Ft. Hood Shooting
A senior officer says the shooter had been getting help for depression and anxiety before he opened fire on fellow soldiers yesterday and eventually killed himself.
Investigators say they'll search his home and computers and interview his widow. They also want to talk to witnesses about whether there was a fight or argument on the base before the attack.
Within hours of the attack, investigators started looking into whether his combat experience caused post-traumatic stress.
