California Jail Suicides and Fentanyl Overdoses Have Been at Historic Highs
Last year, a watchdog group published an article about inmate deaths in California jails. In 2022, a total of 215 people died in the local jails in the state, which was a new annual high. That year, the counties of San Diego, Kern, Tulare, San Bernardino, and Riverside also set records. One of the questions asked was why so many inmates are dying in county jails in California.
After interviewing a wide range of individuals within the California jail system, several patterns emerged. One of the foremost authorities on custodial deaths said that the vast majority of the suicides she looked at in California jails were preventable.
Recent data saw an increase in accidental deaths, including fentanyl overdoses, which accounted for 43 of the inmate deaths in 2022. The San Bernardino County Sheriff, Shannon Dicus, and other sources shared some of the ways drugs have been getting into the jails, namely:
- Many inmates hide opiates in their rectum, which body scanners don’t detect. These people get booked and housed in a general housing unit, where they suddenly have multiple fentanyl overdoses.
- Mail dipped in methamphetamine or fentanyl has been sent to inmates.
- Jail deputies in two California counties have been charged with smuggling drugs into jail.
- A grand jury in Alameda County found that a medical director for the county’s jails had been obtaining opioids for herself by writing fake prescriptions.
In the San Diego County jail system, 47 inmates died between 2021 and 2023. This was at a time when there was resistance to more closely monitoring jail employees. The recent sheriffs have refused numerous requests by a local civilian law enforcement group to put their deputies through scanners before starting their shifts.
In 2023, two deputies pled guilty to drug-related charges, one for burglary of prescription medications at a jail and the other for the possession of drugs on jail property, namely cocaine.
There are significantly fewer people in California jails now than there were as far back as 2005 up through 2019, and yet there are more inmate deaths now. Many things were found to be inconclusive in this investigative story, but the State Auditor’s Office did conclude that the San Diego County Sheriff’s Department failed to prevent death in its jails and that its practices probably contributed to custodial deaths.
