FORT HOOD, Texas (AP) - The senior officer at Fort Hood says the mental condition of the soldier who fatally shot three soldiers and wounded 16 others earlier this week was not the "precipitating" factor in the shooting.
    
The comments Friday by Lt. Gen. Mark Milley came a day after he said Spc. Ivan Lopez's mental condition appeared to be an underlying factor.
    
Milley said Friday that an "escalating argument" precipitated the attack.
    
Authorities say their investigation has found Lopez had an altercation Wednesday with soldiers in his unit that prompted the shooting.
