A 27-year-old California State Prison, Solano inmate was stabbed with an “improvised weapon” and died Wednesday and two other inmates are now under investigation, state prison officials said.
California Department of Corrections and Rehabilitation say the incident began at 7:40 a.m. when staff responded to an ongoing attack in the Facility B recreation yard at the prison. A news release said inmates Christian M. Dumas, 24, and Stephen J. Archer II, 38, were attacking inmate Brenton G. Kinzebaw.

Kinzenbaw was transported to the institution’s triage and treatment area where he was pronounced deceased by prison medical staff at 8:15 a.m.”
No staff or additional inmates were injured and state officials said prison officers recovered one improvised weapon at the scene.

Dumas and Archer have been placed in restricted housing pending an investigation by the prison’s Investigative Services Unit and the Solano County District Attorney’s Office, the release states. The Office of the Inspector General was notified, and the Solano County Coroner will determine Kinzenbaw’s official cause of death.
Kinzenbaw was most recently returned from parole with a new sentence from San Diego County on Sept. 13, 2023. He was sentenced to five years, four months for assault with force likely to produce great bodily injury as a second striker under the state’s three-strikes law, as well as evading or attempting to evade a peace officer while driving recklessly as a second striker. According to media reports, the former Alpine resident was arrested in March 23 after driving a stolen pickup truck toward law enforcement officers near El Cajon. Investigators said he accelerated the truck toward the deputies, nearly striking them, then was shot in his legs by one of the deputies. Kinzenbaw continued driving, but lost control of the truck, crashed it and was arrested, according to San Diego police.
