The fires come every year now. Driven by Santa Ana winds, fueled by drought-dried brush, and accelerated by the steep topography of Los Angeles County’s hillside communities, wildfires have become a recurring mass casualty event.

For the Los Angeles Coroner’s Office, wildfire deaths present a unique and agonizing forensic challenge. The same fire that kills also destroys the evidence needed to identify the dead. Remains are burned beyond recognition. Dental work is damaged by heat. DNA is degraded by the temperatures. Personal effects — the wallet, the phone, the jewelry that might provide a starting point for identification — are melted or consumed.

The work of recovering and identifying wildfire victims is among the most technically demanding and emotionally draining tasks the office performs.

The Recovery

Wildfire death recovery does not begin until the fire is out and the scene is safe. This can take days. Smoldering debris, unstable structures, and toxic materials create hazards that prevent immediate access. The coroner’s investigators wait, knowing that the longer they wait, the more the scene degrades.

When access is granted, the recovery teams work systematically. The burn area is gridded. Each structure is searched methodically, starting with the areas where occupants were most likely to have been — bedrooms, bathrooms, hallways near exits. The search is painstaking because burned remains can be difficult to distinguish from surrounding debris.

Remains found in fire scenes are often fragmentary. Extreme heat reduces bone to calcined fragments. Soft tissue is consumed entirely. What remains may be scattered across a wide area by structural collapse, water from firefighting operations, and wind.

Each fragment is documented, photographed, and collected. The location within the structure is recorded precisely, because the position of the remains relative to exits, bedrooms, and other features provides information about the circumstances of death — whether the person was asleep, attempting to flee, or trapped.

The Identification Challenge

Standard identification methods struggle in wildfire cases. Visual identification is impossible when remains are severely burned. Fingerprints are destroyed along with the skin. Dental remains may survive but can be damaged by temperatures that crack teeth and melt restorations.

DNA offers the best chance, but it is not guaranteed. Extreme heat degrades DNA, and the degree of degradation depends on the temperature, the duration of exposure, and the condition of the bone. Tooth roots and the interior of dense bones — femurs, tibias — offer the best chance of surviving DNA, because they are insulated from the worst of the heat.

The identification process relies heavily on antemortem data from families. Dental records are requested from the victims’ dentists. Medical records are obtained to identify surgical implants, prosthetics, or other medical devices that might survive fire. Family members provide DNA reference samples for comparison.

Forensic anthropologists play a critical role. They can determine the number of individuals present in commingled remains, estimate biological profiles from fragmentary skeletal elements, and distinguish human bone from animal bone — a non-trivial task when household pets are also killed.

The Rapid DNA Labs

Recent wildfire events have prompted the deployment of rapid DNA identification technology. Portable DNA analysis instruments can generate profiles in hours rather than the weeks required by traditional laboratory methods. This acceleration is critical when hundreds of families are waiting for confirmation of their loved ones’ deaths.

The technology has limitations. It works best with well-preserved samples and may fail with severely degraded DNA. But for cases where viable DNA can be extracted, rapid identification dramatically reduces the waiting period for families and allows the investigation to proceed faster.

The Family Assistance Centers

Large wildfire events trigger the activation of family assistance centers — centralized locations where families of the missing can report their loved ones, provide antemortem identification data, and receive updates on the investigation.

These centers are staffed by coroner’s investigators, victim advocates, mental health counselors, and administrative personnel. The atmosphere is one of controlled anguish. Families arrive hoping for news. Some receive confirmation that their loved one has been identified among the dead. Others wait in a limbo that stretches for days or weeks as the identification process works through the most challenging cases.

The staff at these centers bear an emotional burden that compounds over time. Each family interaction requires compassion, precision, and honesty. Families want answers immediately. The science cannot always provide them on that timeline. Managing expectations while maintaining trust is a skill that no training fully prepares someone for.

The Cause of Death

Determining cause of death in wildfire cases involves more than documenting burn injuries. The forensic pathologist must determine whether the victim was alive when the fire reached them or had already died from smoke inhalation, carbon monoxide poisoning, or thermal injury to the airway.

The distinction matters. A victim who was alive and conscious when the fire arrived experienced a different death than one who was overcome by smoke while sleeping. Carbon monoxide levels in the blood — if blood is available for testing — can indicate whether the victim was breathing in a smoke-filled environment. Soot in the airways indicates the same.

In some cases, the fire masks another cause of death entirely. A homicide victim placed in a structure that is then set ablaze. A person who died of a medical event and was then consumed by a fire that swept through the area hours later. The forensic pathologist must consider these possibilities and look for evidence that the fire is concealing something else.

The Increasing Frequency

Climate change, urban expansion into fire-prone areas, and aging infrastructure have made wildfire deaths a growing component of the coroner’s caseload. What was once an occasional event has become a seasonal expectation.

The office has adapted. Mass fatality plans have been updated to specifically address wildfire scenarios. Equipment and supplies for fire-scene recovery are pre-staged. Staff have received specialized training in burned remains recovery and identification. Mutual aid agreements with other jurisdictions ensure that additional resources can be mobilized quickly.

But adaptation has limits. Each major fire event strains the office’s capacity, pulling resources from routine operations and imposing physical and emotional costs on staff who may have been personally affected by the same fire they are investigating.

The Record

The coroner’s records of wildfire deaths serve a purpose beyond individual case resolution. The data — how many died, where they died, whether they were attempting to evacuate, whether they had received warnings — informs future fire preparedness.

Patterns emerge from the data. Elderly residents and those with mobility limitations are disproportionately represented among wildfire deaths. Deaths cluster in areas where evacuation routes were blocked or where warning systems failed to reach residents. People who sheltered in place died at higher rates than those who attempted to evacuate, contradicting some public safety messaging.

This data has been used to argue for improved evacuation planning, better notification systems, stricter building codes in fire-prone areas, and enhanced support for vulnerable populations during fire events.

The coroner’s office, as always, provides the data. What the living do with it is up to them.
