Geronimo Pratt joined the Black Panthers shortly after his service in the army. Pratt proved to be a rising star in the Party, so much so that the FBI feared him. Pratt was heavily targeted under the FBI Counter Intelligence Program (COINTELPRO). Pratt is perhaps most well known for having been convicted of murder in 1972, for the murder of Caroline Olsen. By and large, Pratt’s conviction was sealed by the testimony of a police informant and Panther infiltrator who was likely planted by the police or the FBI. In 1997 his sentence was voided, citing a suppression of evidence by the prosecution. After prison Pratt did not disappear from the public eye and became an advocate for wrongfully convicted people.
