Sgt. Kimberly Munley, the cop who took down Maj. Nidal Hasan

Sgt. Kimberly Munley is described, by neighbor Brooke Beato, as "very petite, with long blond hair and a strong personality,"

That strong personality propelled her to be first to the bloody scene where U.S. Army Major Nidal Hasan was berserking. She arrived within a few minutes after he went into attack mode and is credited by base officials with stopping him and preventing additional carnage.

The Star Tribune reports:

Hasan, an Army psychiatrist, had already killed or wounded dozens of soldiers, according to Army officials. He was still firing at unarmed troops who were dragging away their bleeding colleagues when he locked his eyes on Munley, raised his pistols and charged her.

Sgt. Munley immediately and aggressively engaged him as he shot at her. She was shot three times as she ran to confront him and at least one of her rounds is said by witnesses to have hit him in the chest, bringing him to the ground.

In the hospital, recovering from wounds to both thighs and one wrist, Sgt. Munley spent the time not in self-congratulatory satisfaction, but in serious reflection coupled with remorse over those she was too late to save.

TIME.COM reports:

Soon after Munley fired at Hasan, taking him down, she herself fell wounded and police radios quickly sent out an "Officer down" call. Wounded three times in the arm and leg, Munley is in stable condition after undergoing surgery Friday to repair damage to an artery. Base officials said she wishes she could have acted even faster and saved more lives, and she spent Thursday evening calling friends and colleagues, expressing those regrets.

To that description of Sgt. Munley, given by her neighbor, I would add inspiring.
