When a body is found in California without identification, the county coroner or medical examiner takes custody and begins a forensic investigation on a strict statutory clock: law enforcement has 10 days to report the death to the state, the coroner has 45 days to submit dental records and 180 days to file a complete investigation report, and DNA, dental, and tissue samples must be collected before the remains can be buried or cremated. If no match surfaces, the county arranges disposition, usually a cremation or burial in a county plot, but the forensic file stays in state and national databases so an identification can still happen years later.
What the Coroner Collects From the Body
The postmortem exam is built around capturing every identifier that could later tie the remains to a name. Investigators record fingerprints and palm prints, photograph the face from the front and side, and document scars, tattoos, birthmarks, and other distinguishing features. A qualified dentist charts the teeth and takes dental X-rays. Tissue and fluid samples, including hair and bone, are collected for DNA analysis. The file is assembled in a format the California Department of Justice prescribes, so it can be compared against missing-person records statewide and nationally.1Commission on State Mandates.

Under Penal Code Section 14250, the coroner must collect a DNA sample from the remains and deliver it to the DOJ for analysis before any burial or cremation. The resulting profile is uploaded to the state database and to the FBI’s Combined DNA Index System (CODIS).2California Legislative Information. California Penal Code PEN 14250
The Reporting Deadlines
California staggers its deadlines by the type of evidence involved. Local law enforcement must report the death to the DOJ within 10 calendar days of discovery. If the coroner still cannot establish identity, dental charts and X-rays must reach the DOJ within 45 days. The coroner’s final investigation report is due within 180 days of the discovery date.1Commission on State Mandates.

Which Databases Get Searched
Once the forensic data reaches the DOJ, the Missing and Unidentified Persons Section compares fingerprints, dental and body X-rays, photographs, and physical descriptions against the statewide missing-person files.3State of California Department of Justice – Office of the Attorney General.

On the DNA side, the DOJ’s Missing Persons DNA Program runs the unidentified profile against two reference pools: DNA pulled from personal belongings of missing people (a toothbrush, for example) and DNA voluntarily submitted by relatives.4California Department of Justice.

Missing and Unidentified Persons Section
Cases are also cross-referenced with the National Missing and Unidentified Persons System (NamUs), a federally funded, publicly searchable database. NamUs lets investigators in one jurisdiction check unidentified remains against a missing-person report filed in another state.
What Happens When Identification Fails
If every lead has been exhausted, the coroner authorizes final disposition. Nothing can move forward until the required DNA, dental, and tissue samples have been collected. In most California counties, the remains then enter the county’s indigent disposition process, which typically means direct cremation or burial in a county-designated plot without ceremony. Some counties hold cremated remains in a vault for a set period, such as six months, before scattering them.
The county pays for this. Coroners are often reluctant to authorize disposition while any lead is still open, because exhuming remains for additional testing later is expensive and logistically difficult. The practical result is that some unidentified individuals stay in cold storage at the coroner’s office for years before anything final happens.
The Case File Stays Open After Burial
Disposition does not close the investigation. The dental records, photographs, fingerprints, and DNA profile remain in DOJ and federal databases indefinitely. A match can surface decades later if a relative submits a reference DNA sample or if forensic genealogy connects the profile to a family tree.
DNA submitted by living relatives is treated differently from the remains’ own sample. Under Penal Code Section 14250, relative samples and any profiles developed from them must be destroyed once a positive identification is made and a report is issued, unless the death is suspected to involve criminal conduct.2California Legislative Information.

If You’re Searching for a Missing Loved One
The first step is filing a missing-person report with your local law enforcement agency. California police must accept the report immediately; there is no waiting period. Filing puts the person’s information into the DOJ’s Missing Persons System, where it is compared against unidentified cases statewide.
You can also search NamUs directly. It is open to the public and includes case details, photographs, and physical descriptions of unidentified individuals from across the country. Families can submit reference DNA samples to the DOJ’s Missing Persons DNA Program at no cost, and those samples are compared against every unidentified profile in the state database and in CODIS.4California Department of Justice. Missing Persons DNA Program FAQ
To add a missing person’s dental records, X-rays, photographs, or fingerprints to the DOJ’s systems, the family generally needs to authorize their release. The DOJ’s Missing and Unidentified Persons Section coordinates these efforts and can help families and law enforcement work across jurisdictions.3State of California Department of Justice – Office of the Attorney General.
