Deaths in jail custody are always tragic, but when they occur repeatedly — especially under similar circumstances — families, advocates, and oversight groups understandably raise serious questions about how and why these fatalities happen. In Riverside County, California, a pattern of in-custody deaths over the past several years has sparked lawsuits, legal scrutiny, and public criticism, particularly around transparency, supervision, and compliance with state law. 
Recent In-Custody Fatalities Continue to Occur
Riverside County jails reported multiple inmate deaths between 2024 and 2025. According to official sheriff’s department notices, detainees have been found unresponsive in their cells or during medical emergencies across county facilities such as Robert Presley Detention Center, Larry D. Smith Correctional Facility, and the Cois Byrd Detention Center. Often, deputies and medical staff administered lifesaving measures, but in many cases the individuals were ultimately pronounced deceased at the scene or after transport to a hospital.
While these incidents include instances with no signs of foul play and others potentially stemming from suicides or medical conditions, their frequency is a concern for families and advocates.
High Death Counts Call for Transparency and Oversight
Riverside County’s jail death toll was particularly worrisome in 2022, when 18 inmates died in custody, one of the highest annual counts in recent memory. That spike contributed to public outcry and academic analysis showing that Riverside County had one of the deadliest jail systems in the nation among large counties for the period between 2020 and 2023. Nonprofit research also counted hundreds of in-custody deaths in Riverside County over the past decade.
Lawsuits Over Deaths and Classification Failures
Several families of individuals who died in Riverside County custody have filed civil rights or wrongful death lawsuits, alleging that the county and its sheriff’s department were negligent in protecting their loved ones. One notable example alleged the county misclassified a violent inmate, placing him with another detainee whom he ultimately killed.
In other lawsuits, relatives have alleged failures to conduct consistent safety and welfare checks, inadequate medical care, or negligent supervision — all of which can be actionable under federal civil rights law when they amount to constitutionally deficient conditions of confinement.
Transparency Lawsuit: Alleged Violations of Public Records Requirements
Another significant legal issue Riverside County faces is the county’s response to in-custody deaths with transparency and public reporting.
In late 2025, the First Amendment Coalition (FAC) — alongside investigative journalist Christopher Damien and The New York Times Company — filed a lawsuit against Riverside County alleging violations of the California Public Records Act (CPRA) and Senate Bill 519.
SB 519, which took effect in 2024, was specifically enacted to improve transparency surrounding in-custody deaths by requiring detention facilities to make related investigative records available to the public. SB 519 mandates that records related to in-custody death investigations — such as coroner reports and internal review findings — be accessible under standard public records rules.
However, the FAC lawsuit alleges that Riverside County withheld, delayed, and improperly redacted responsive records, failing to produce coroner reports and other materials about dozens of in-custody fatalities. According to the complaint, the county continued to withhold records about 13 in-custody deaths and charged unauthorized processing fees, contrary to CPRA requirements.
The FAC’s action presents a broader transparency problem: even when laws require disclosure of information about in-custody deaths, families and journalists are often unable to obtain the documentation needed to understand the causes and circumstances of these deaths.
Calls for Independent Death Investigations
Beyond transparency lawsuits, civil rights advocates have also pushed for changes to the way in-custody deaths are investigated in Riverside County. In several counties across California, the sheriff also serves as the coroner — meaning the same official overseeing the detention facility may also control the death investigation process. Critics argue this poses a conflict of interest, especially when a death occurs in custody or in an incident involving law enforcement.
For example, following the death of Richard Matus Jr. in a Riverside jail, advocates argued that separating the offices of sheriff and coroner is necessary to ensure impartial and thorough death investigations that families and the public can trust.
Why These Legal Issues Matter
The legal challenges facing Riverside County aren’t abstract. They have real impacts on:
- Family access to information about custody deaths
- Public accountability and oversight of jail practices
- Policy reforms related to classification, monitoring, and medical care
- Civil liability and financial accountability for counties and their sheriffs
Conclusion
In-custody deaths in Riverside County have prompted lawsuits, public criticism, demands for independent oversight, and a high-profile lawsuit over transparency under California law. These legal troubles reflect deeper challenges in how the county’s jails are operated and monitored — from classification and welfare checks to reporting and public accountability. Families affected by in-custody deaths deserve clear answers and transparent investigations. Where the law requires disclosure and the public faces obstacles, legal action becomes a necessary tool to enforce transparency and accountability.
