In summary
The California Legislature passed a bill that would force disclosure of information about emergency calls at immigrant detention centers. A Democratic lawmaker put it forward after reading news stories in CalMatters.
Legislation that would improve public access to information about violence, medical emergencies, and other serious incidents in privately operated detention facilities in California is now heading to the governor’s desk.
It would require local agencies to release audio and records of 911 calls and other emergency-service calls originating from the facilities upon request. State Sen. Lena Gonzalez, a Democrat from Long Beach, introduced Senate Bill 423 as state investigations and courts are finding serious gaps in essential medical care within the facilities.
“No private contract or detention center wall should be used to hide dangerous conditions or silence people who have been mistreated inside these facilities,” Gonzalez said in a statement.
The bill was prompted by CalMatters reporting on alleged sexual assaults at the Otay Mesa Detention Center in 2025. CalMatters sought information, including 911 audio records and other reports, about alleged rapes and attempted sexual assaults at the facility through a California Public Records Act request. While a San Diego County sheriff’s spokesperson said the agency was not investigating those cases, he said he was unable to turn over additional records because they were part of “a law enforcement investigation.”
“When journalists and reporters attempted to obtain records about reported incidents at these facilities through the Public Records Act, they faced severe pushback from law enforcement, citing vague investigatory records exemptions, despite there being no active investigation,” said Gonzalez before the state Senate vote on Monday afternoon.
“SB 423 would make disclosure mandatory for calls from private detention facilities unless it would substantially interfere with an active investigation being conducted by the agency receiving the request,” she added.
Gonzalez’s bill would require local agencies to turn over recordings and written records of 911 calls from privately run detention facilities, if a member of the public requests them. It includes an exception if an active investigation is underway and requires redacting the names of affected individuals.
The number of people being held by federal immigration authorities in Immigration and Customs Enforcement facilities in California has nearly doubled since early 2025, data shows. Between September 2025 and March 2026, there were six deaths at two of California’s private detention facilities.
The San Diego County Sheriff’s Office had a memorandum of understanding with CoreCivic, the private prison company that operates Otay Mesa. The agreement gave the detention center warden discretion of how to investigate alleged sexual assaults.
In May, the California Attorney General’s office released a 175-page report detailing how the dramatic surge in detainee populations strained conditions and access to medical care at immigration detention facilities across the state.
The San Diego County Sheriff’s Office told KQED it does not have a position on the bill. The Kern County Sheriff’s Department told the Bay Area news agency that it will continue to comply with California laws, “as we always do.”
A recent bill analysis by legislative staff showed no registered opposition to the bill.
The proposed legislation was co-sponsored by Immigrant Defense Advocates and the First Amendment Coalition. It was first introduced on June 12.
Paloma Esquivel, a former Los Angeles Times reporter who now works at the First Amendment Coalition, said county sheriffs resisted and stonewalled her requests for 911 records when she worked as a journalist.
“We have a very strong interest and even an obligation to understand how these facilities are functioning and what is happening inside these facilities that are being paid for with billions of dollars in taxpayer money,” Esquivel told KQED.
Jackie Gonzalez the co-executive director of the Immigrant Defense Advocates said the bill is an important first step in addressing what’s going on inside.
“By supporting SB 423, California sends a clear message that the walls of private detention facilities cannot hide the truth of what is taking place in these facilities,” said Gonzalez.
