The former Black Panther Party leader Geronimo Pratt has passed away. Pratt became a political prisoner after he was convicted in in 1972 for a murder he did not commit, and his life came to symbolize bitter racial injustice and the state-organized oppression of black resistance after he spent 27 years in prison for that crime. His conviction was overturned in 1997.

“Geronimo was a symbol of steadfast resistance against all that is considered wrong and improper,” his friend Pete O’Neal told NPR. “His whole life was dedicated to standing in opposition to oppression and exploitation. … He gave all that he had and his life, I believe, struggling, trying to help people lift themselves up.”

After his release, Pratt had moved to Tanzania, where his friends and family say he devoted his life to the local community and the United African Alliance Community Center, and lived with his wife and family. He was 63.

Here now, a quick look back at the turmoil of Pratt’s life in images. For more history, check out this Los Angeles Times account from 2008 of the 1968 murder of Caroline Olsen all the way up to Pratt’s eventual exoneration.

Pratt was convicted in 1972 of the 1968 murder of a 27-year-old schoolteacher on a Santa Monica tennis court and wounding her husband in a mugging. Pratt maintained his innocence especially since he was in Oakland when the crime took place. Johnnie L. Cochran, Jr. along with

Stuart Hanlon became the two key attorneys on his case.

Pratt was granted a new trial in 1997 after a Orange County Superior Court Judge

ruled that prosecutors had concealed evidence that could have led to an acquittal. The Court of Appeal panel affirmed that judge’s decision in 1999.

“Years

would pass before it finally came to light that he’d been targeted by

J. Edgar Hoover and a systematic FBI counter-intelligence program whose

admitted goal was to undermine black solidarity and “neutralize” Panther

leaders.”
