Army Officials: Fort Hood Shooter Showed No Signs Of Violence
Army officials say the soldier who killed three people at Fort Hood and then committed suicide saw a psychiatrist last month, and showed no "sign of any likely violence either to himself or others."
Officials say there's a "strong possibility" that Spc. Ivan Lopez had an argument with at least one soldier right before Wednesday's shooting.
Investigators are looking into Lopez's psychological background. Officials say he never saw combat during a deployment to Iraq.
