Fort Hood Shooting: Gunman Leaves 3 Dead

Fort Hood Shooting

Tragedy strikes again at Fort Hood in Killeen, Texas. 

Less than five years after an Army psychiatrist went on a shooting rampage at the military base, Fort Hood was shaken by another shooting.

CNN reports that on Wednesday at around 4 p.m., specialist Ivan Lopez went from one building at the sprawling military base to a second, firing a .45-caliber handgun. Over the next 15 to 20 minutes, he killed three people and wounded 16 others. The 34-year-old soldier then ended his own life. 

Although his motive remains unknown, initial reports indicate that there may have been an argument in one of the unit areas, according to Lt. Gen Mark Milley, the post's commanding general. 

Lopez, who previously served in the Army National Guard in Puerto Rico, served as an active duty soldier in the U.S. Army at the time of the shooting, and was assigned to the 13th Sustainment Command at Fort Hood, NBC News reports. He served one tour of duty in Iraq, and underwent diagnosis procedures for PTSD. Although he was not wounded in action in Iraq, he self-reported a brain injury after returning from his tour of duty. 

The gunman moved into an apartment in the area three weeks ago with his wife and young daughter. A neighbor told a local NBC affiliate that the family seemed "real sweet." 

More details to come.
