After Sgt. Kimberly Munley helped stop the Fort Hood massacre by shooting Major Nidal Malik Hasan several times, she collapsed from her wounds and doctors who treated her were afraid she wouldn't survive.
"She was fading in and out of consciousness. She wasn't saying much," medic Francisco de la Serna, who began treating Munley when the shooting stopped, told ABC News.
Munley, a 34-year-old former soldier who became a civilian cop on the Fort Hood base, was shot twice in both legs during Thursday's confrontation. Two powerful "cop killer" rounds allegedly fired by Hasan tore through her left thigh, exited and blasted through her right thigh as well. She was also struck in the wrist.
Sgt. Mark Todd, 42, a retired soldier who also works as a civilian police officer at Ford Hood, also engaged in a firefight with Hasan that lasted less than a minute, according to The Associated Press. Todd was not wounded.
Army officials say that an investigation is under way about whose bullets brought down Hasan as there was much confusion following the shooting. Munley's supervisor initially credited her with the shot that stopped Hasan.
Todd told The Associated Press Saturday that he was unsure if Munley had wounded the suspect, because "once he started firing at me, I lost track of her."
After firing his Beretta at Hasan, Todd said the suspect flinched, slid down against a telephone pole and fell on his back. Todd recalls hearing people say, "two more, two more." He first thought they were referring to more shooters, but he realized that the bystanders were urging him to fire two more rounds, Todd said.
Todd said he approached the suspect and saw that he still had a gun in his hand, which he kicked away. Todd told the AP, "He was breathing, his eyes were blinking. You could tell that he was fading out. He didn't say anything. He was just kind of blinking."
Munley, the mother of two girls, was sped to Metroplex Hospital several miles away where doctors say she lost so much blood that they feared she would not make it.
Munley proved to be as tough in the operating room as she was while confronting Hasan in their close-range shootout.
Dr. Kelly Matlock, who treated Munley at the Metroplex Hospital, said her first words in recovery were concern about Hasan's victims.
"She opened her eyes and said, 'Did anybody die?' That's what she said, 'Did anybody die?'" Matlock said.
Munley now knows that the man she shot is alive, and that he is accused of killing 13 unarmed people and wounding 38.
Texas Gov. Rick Perry visited Munley in the hospital today and later described her as "understated."
"She is a classic public servant who is not interested in anything other than getting on with her life," Perry said.
Chuck Medley, the director of emergency services at Fort Hood, said many more would have died if Munley had not leaped into action.
"If she had not responded the way she had, we would have had an extremely high number of dead and injured," Medley told ABC News Friday. "The number of lives that this person saved ... We will probably never know. But there is a lot of ammunition left, a lot of magazines," he said referring to what Hasan was allegedly carrying.
