Fort Hood Shooter ID

The soldier responsible for Wednesday's deadly shooting at Fort Hood never saw combat in Iraq.  Army Secretary John McHugh told the Senate Armed Services Committee today Specialist Ivan Lopez served as a truck driver in Iraq for four months. He said Lopez bought the weapon used in the shooting off base and never registered it with the post. Lopez took his own life after killing three fellow soldiers at the army base, and injuring 16. Lt. General Mark Milley says a memorial service will be held next week to honor the victims.
