The hero cop who ended the bloody rampage at Fort Hood had been directing traffic moments before she confronted the gunman and pumped four bullets into him despite being shot herself.

Civilian police Sgt. Kimberly Munley and her partner responded within three minutes of reported gunfire Thursday afternoon, Lt. Gen. Bob Cone said Friday.

Munley, who had been trained in active-response tactics, rushed into the building and confronted the shooter as he was turning a corner, Cone said.
