SAUSALITO, Calif. — Afeni Shakur Davis, the mother of one of hip-hop’s most seminal and iconic figures, died at age 69, the Marin County, California, sheriff’s office said Tuesday.

Though she is best known as Tupac Shakur’s mom, she was also a Black Panther as a young adult and an activist in later years.

Deputies responded to a call reporting “a possible cardiac arrest” at her Sausalito home around 9:34 p.m. Monday, the Marin County Sheriff’s Office said.

Shakur Davis was taken to the hospital where she died at 10:28 p.m., the office said.

“Sheriff’s Coroners Office will lead investigation to determine exact cause & manner of Afeni Shakur’s death,” the office said in a tweet.

Information is still being gathered, and the sheriff’s department will answer questions regarding her death later Tuesday morning, it said.
