Assata Shakur, a famed political activist who was found guilty of shooting a New Jersey state trooper in 1973 and later granted political asylum in Cuba, has died. She was 78.

On Thursday, Shakur “died in Havana, Cuba, as a result of health conditions and her advanced age,” according to Cuba’s Ministry of Foreign Affairs.

“At approximately 1:15 PM on September 25th, my mother, Assata Shakur, took her last earthly breath. Words cannot describe the depth of loss that I am feeling at this time,” Kakuya Shakur, her daughter, wrote on Facebook.

“I want to thank you for your loving prayers that continue to anchor me in the strength that I need in this moment. My spirit is overflowing in unison with all of you who are grieving with me at this time.”
