The top commander at Fort Hood is crediting a civilian police officer for stopping the shooting rampage that killed 13 people at the Texas post.

Lt. Gen. Bob Cone said Friday morning that Sgt. Kimberly Munley and her partner responded within three minutes of reported gunfire Thursday afternoon. Cone said Munley shot the gunman four times despite being shot herself.

Military officials said Munley was in stable condition Friday.

Cone said, "It was an amazing and an aggressive performance by this police officer."

Cone also said he was inspired by a woman who helped carry a wounded victim and used her blouse as a tourniquet, then realized she'd been shot in the hip.

The suspected gunman, Maj. Nidal Malik Hasan, is hospitalized on a ventilator.
