The activist and philanthropist suffered possible cardiac arrest at her home in Marin County, California, and was transported to a hospital, where she died last night.

Afeni, who had been part of the Black Panther movement in the 1960s, was the executor of her son's estate following his murder in 1996, and set up the Tupac Amaru Shakur Foundation, which established artistic programs for young people, as well as the Tupac Amaru Shakur Center for the Arts in Atlanta.
