Deaths of individuals while in law enforcement custody remain a pressing concern in California. Despite a recent significant decline in jail and prison populations, the number of people dying in county jails has remained at historically high levels, driven by suicides, drug overdoses, medical emergencies, and related causes.

Overview — A Persistent Crisis Amid Falling Populations

Contrary to what many policymakers once predicted, fewer inmates in jail has not translated into fewer deaths. California’s jails recorded higher in-custody death rates even as overall population trends decreased, with counties large and small reporting fatalities due to suicide, overdose, and natural causes.

Experts have highlighted that while local sheriffs sometimes attribute deaths to underlying health conditions rather than custody environments, others point out that inadequate care, poor mental health support, and lack of monitoring are significant contributors. 

Data & Trends: California Jail Deaths on the Rise

Statewide Patterns

California counties have experienced record and near-record numbers of deaths in local detention facilities:

• In 2022, county jails across California reached a peak of 215 in-custody deaths, the highest in recent years. Even as the incarcerated population declined, death rates stayed elevated through 2023 and 2024.
• Officials established a new in-custody death review staff position under a law that went into effect in 2024 to improve transparency and reporting; statewide mortality data is now being made publicly available. 

Why Are People Dying in Custody?

California’s in-custody deaths span a range of causes:

1. Overdose and Substance Issues

Overdoses cause numerous fatalities inside California jails, exacerbated by the prevalence of synthetic drugs like fentanyl.

2. Suicide & Mental Health

Suicide and self-harm are deeply troubling components of jail death statistics, often linked to inadequate mental health care and supervision.

3. Natural Causes & Medical Emergencies

Many incarcerated individuals suffer from chronic health conditions that require consistent care, and delays in diagnosis or treatment while in custody often result in preventable deaths. 

Legal & Oversight Framework in California

Mandatory Reporting & Review

Under California Government Code § 12525, law enforcement agencies and sheriff’s departments must report all in-custody deaths — including those in city and county detention facilities — to the State Department of Justice’s Criminal Justice Statistics Center.

This reporting requirement helps create transparent statewide tracking of mortality in custody and help find patterns in need of policy change.

Investigations & Accountability Layers

When an individual dies in custody, multiple reviews may occur depending on the circumstances:

• Internal investigations by the law enforcement agency responsible for the facility. 
• External reviews by oversight bodies, inspector generals, or county coroners, especially when foul play, neglect, or inadequate care is suspected.
• Civil liability claims by families may arise when deaths are linked to negligence in medical care, supervision failures, or conditions that fall below constitutional standards.

Civil & Constitutional Claims Families May Pursue

Families of people who die in custody may have legal causes of action under state and federal law, including:

• Wrongful death claims asserting that inadequate healthcare, supervision, or facility conditions caused or contributed to a preventable death.
• Civil rights claims under 42 U.S.C. § 1983 when conduct by jail or prison staff violates constitutional protections — such as deliberate indifference to serious medical needs (a violation of the Eighth Amendment when the individual is convicted, or the Fourteenth Amendment during pre-trial detention).
• Claims for negligent supervision, failure to train, or inadequate policies when systemic deficiencies in jail operations contribute to unsafe conditions.

What Families Should Do If Loved Ones Die in Custody

If a loved one dies while in jail or prison custody:

1. Request all official records — incident reports, medical records, autopsy reports, and video footage.
2. Seek an independent investigation — including coroner findings and any external review board reports.
3. Preserve evidence quickly — documentation and physical evidence can disappear if not secured early.
4. Consult experienced legal counsel — civil rights and wrongful death cases in custodial settings require specialized legal knowledge.

Seeking Accountability For In-Custody Deaths

California’s in-custody death rates have continued to rise despite falling inmate populations and reforms aimed at improving oversight. Record or near-record numbers of fatalities in county jails reflect larger systemic issues,  from inadequate medical and mental health care to failures in supervision and crisis response.
