A former Weather Underground radical who served more than two decades behind bars for her role in a fatal 1981 armored truck robbery has died at age 78.
Kathy Boudin died of cancer Sunday surrounded by family.
She had lived in New York City since her release from prison in 2003.
Boudin had expressed remorse for the infamous Brink's robbery, in which a guard and two police officers were killed north of New York City.
Boudin kept a low profile after her release and continued to work on behalf of inmates and former inmates.
Her death was confirmed by Chesa Boudin, her son and San Francisco's district attorney.
