FORT HOOD, Texas (AP) - An Iraq War veteran who authorities say killed three people and wounded 16 others at Fort Hood was being treated for mental illness.

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.
