Marvin’s Brochure


Shaka Nantambu is the loving son of Emma Lou Walker and Marvin Pete Walker, and the oldest son of 10 siblings. His family includes many great and great-great nieces and nephews who would benefit from his presence in their lives. He has lived on in San Quentin for over 40 years, since he was 19 years old. In the summer of 2020 he was hospitalized with COVID-19 after the CDCR moved several COVID positive inmates to San Quentin. Later that summer his conviction was overturned for the second time because of racist prosecutorial misconduct. He is currently serving 25 years to life and expects to go before the parole board soon.
