Joka Heshima Jinsai, legally Shannon Lemar Denham, is an incarcerated writer and community organizer associated with the Autonomous Infrastructure Mission and the campaign to end the Thirteenth Amendment’s punishment exception. His supporters describe work on community food, education and economic initiatives. He has challenged prolonged segregation linked to political expression. CDCR listed him at Kern Valley State Prison on September 10, 2026. The case below concerns that prison segregation rather than classifying his original criminal prosecution as activism-related custody.
Counsel’s March 20, 2012 petition, page 18, identifies S. Heshima Denham, CDC J38283, with birth date January 17, 1960. The register matches the prisoner also known as Joka Heshima Jinsai.
Counsel’s 2012 public UN petition reports placement in the SHU on or about August 8, 2000. This is the start of the specifically described isolated-segregation episode within an existing prison term, not a fresh physical admission into prison. The reported start is approximate. The actual end and complete duration of this isolation episode remain unknown; no ongoing solitary-confinement counter or present isolation status is inferred. The report concerns an internal segregation period within his overall incarceration.
