(CNN) – The search for a motive is keeping the Fort Hood shooter's name in headlines. But the focus, ultimately, must be on the lives he took, and the lives he forever changed.

We now know the names of all three men shot and killed at Fort Hood.

Sgt. Carlos Rodriguez was from Puerto Rico and enlisted as soon as he could, at age 18. After serving 20 years, he was reportedly planning to retire soon from the military. He was 38.

Sgt. Timothy Owens was an Army counselor who had served in Iraq. A native of Illinois, Owens had just gotten married in August, and had two children from earlier relationships. He was 37.

Sgt. Danny Ferguson had just returned from Afghanistan. His fiancée, who is also a soldier, says Ferguson was killed trying to hold a door shut to stop the shooter, and likely saved lives.
