KILLEEN, Texas (AP) — A civilian police officer is being praised for taking down a man suspected of opening fire on fellow soldiers at Fort Hood when she shot him in the torso.

Police officials say after arriving at the scene of Thursday's gunfire, Sgt. Kimberly Munley saw the suspect and started firing at him. Munley's boss, Chuck Medley, told The Associated Press on Friday that Hasan then spun around and charged at her with a gun in each hand.

Sgt. Kimberly MunleyMedley says Munley shot the alleged gunman, Maj. Nidal Malik Hasan, in the upper torso, allowing officers to take him into custody. Medley says in the exchange of gunfire, Munley was shot in the thighs and wrist. The 35-year-old Munley is from Pennsylvania, used to be in the Army and is married to a Fort Bragg, N.C., soldier.

There are many unknowns about the man authorities say is responsible for the worst mass killing on a U.S. military base.

Army psychiatrist Nidal Malik Hasan, a suspect in the assault, salved the emotional wounds of troops returning from war even as he objected to his own looming deployment to Afghanistan, where he was to counsel soldiers suffering from stress. But Hasan argued with fellow soldiers who supported U.S. war policy, say those who know him professionally and personally. He was a counselor who once required counseling for himself because of trouble he had dealing with some patients, said a former boss.

Authorities on Friday seized Hasan's home computer, searched his apartment and took away a Dumpster as the 39-year-old Army major lay in a coma in the hospital, attached to a ventilator.

For six years before reporting for duty at Fort Hood, in July, Hasan worked at the Walter Reed Army Medical Center pursuing his career in psychiatry, as an intern, a resident and, last year, a fellow in disaster and preventive psychiatry. He received his medical degree from the military's Uniformed Services University of the Health Sciences in Bethesda, Md., in 2001.

The 13 people included a pregnant woman who was preparing to return home, a man who quit a furniture company job to join the military about a year ago, a newlywed who had served in Iraq and a woman who had vowed to take on Osama bin Laden after the Sept. 11 terrorist attacks.
