MARTINEZ -- A 46-year-old Contra Costa County Jail inmate found dead in his cell in February died of heart failure, according to pathologist's testimony at a coroner's inquest Tuesday.
Pittsburg resident Alvin Jackson was discovered dead by a cellmate around 4:10 a.m. Feb. 1, the day before he was scheduled to be released from the Martinez facility. Jackson had been serving an 83-day sentence for first-degree burglary and a parole violation.
Sheriff's deputies testified they were on Jackson's floor to administer insulin to Jackson and other diabetic inmates when they were alerted that he was cold and unresponsive. Deputies and medical staff attempted lifesaving measures before pronouncing him dead at 4:27 a.m., according to testimony.
The Contra Costa County Sheriff's-Coroner's Office hold inquests into all in-custody and officer-involved deaths. A jury on Tuesday ruled that Jackson died of natural causes.
