Jeanne Assam

Assam is a security guard at New Life Church in Colorado Springs. A year ago, Assam shot a man named Matthew Murray, who had opened fire on worshippers there and killed two teenage sisters. (Not counting the two other victims that Murray killed at a youth center.) After Assam stopped him, Murray killed himself.

The AP has a good piece here about Assam, the shooting survivors and the anniversary of the shootings.
