At 4:31 a.m. on January 17, 1994, the Northridge earthquake struck the San Fernando Valley with a magnitude of 6.7. Within seconds, freeways collapsed, apartment buildings pancaked, and gas lines ruptured into fire. Fifty-seven people were killed.
For the Los Angeles Coroner’s Office, the earthquake was not just a disaster. It was a test of everything the office had prepared for — and a few things it had not.
The dead arrived in waves. Some were recovered quickly from collapsed structures. Others were not found for days. The office had to identify remains, determine causes of death, coordinate with search-and-rescue teams, and manage the expectations of hundreds of terrified families — all while operating from a building that had itself sustained earthquake damage.
Northridge was neither the first nor the last mass casualty event the office would handle. Los Angeles, by virtue of its geography, its density, and its bad luck, has produced a steady stream of disasters that tested the coroner’s mass fatality protocols.
The Protocols
Mass fatality response is fundamentally different from routine death investigation. The volume overwhelms normal operations. The conditions at the scene — fire, structural collapse, contamination — may prevent normal recovery and examination procedures. The political and media pressure intensifies exponentially.
The LA Coroner’s Office maintains a mass fatality plan that details how the office scales up when a disaster produces more deaths than normal operations can handle. The plan covers everything from personnel mobilization to temporary morgue facilities to family assistance centers.
The core challenge is identification. In a mass casualty event, remains may be fragmented, burned, commingled, or otherwise altered beyond visual recognition. The office deploys every identification tool simultaneously — fingerprints, dental records, DNA, personal effects, medical devices with serial numbers, and radiographic comparison of old and new X-rays.
A disaster victim identification team follows systematic protocols adapted from international standards. Each set of remains is assigned a number and processed through a series of stations — photography, radiology, pathology, dental examination, fingerprinting, DNA sampling, and personal effects documentation. The goal is to match postmortem data from the remains against antemortem data collected from families of the missing.
The History
Los Angeles has endured a catalog of mass casualty events that would test any forensic operation.
Air disasters have produced some of the most complex mass fatality operations. The 1986 Cerritos midair collision between an Aeromexico DC-9 and a Piper Cherokee killed 82 people — 67 on the airliner, 15 on the ground when the wreckage struck a residential neighborhood. The 1991 runway collision at LAX between a USAir 737 and a SkyWest commuter plane killed 34. Each crash required the coroner’s office to recover, identify, and process dozens of victims from wreckage fields.
The 1992 riots following the Rodney King verdict produced 63 deaths across Los Angeles County over six days. The coroner’s office processed gunshot victims, fire deaths, and blunt force trauma cases at a pace that pushed operations to capacity. The circumstances of each death — riot-related or coincidental — had to be individually determined.
Wildfires have become an increasingly common mass casualty scenario. The fires that sweep through Los Angeles County’s hillsides and canyons destroy homes and trap residents. Remains recovered from fire scenes are often severely burned, requiring extended identification processes. The 2018 Woolsey Fire, while centered in Ventura County, involved LA County resources and demonstrated the scale of wildfire fatality operations.
The 2015 San Bernardino shooting, while technically in San Bernardino County’s jurisdiction, involved mutual aid coordination with the LA Coroner’s Office. Mass shooting events require rapid processing of multiple victims while maintaining evidence integrity for the criminal investigation that follows.
Temporary Morgue Operations
When the regular morgue facilities cannot handle the volume, the office activates temporary morgue operations. These are set up in large facilities — warehouses, hangars, convention spaces — equipped with portable examination equipment, refrigeration, and communications infrastructure.
Temporary morgues are logistically complex. They require power, water, lighting, ventilation, and biohazard containment. They require staffing from multiple agencies — pathologists, dentists, fingerprint technicians, DNA analysts, radiology technicians, and administrative support. They require supply chains for body bags, examination instruments, specimen containers, and documentation materials.
The office conducts periodic exercises to test its mass fatality plan, simulating disaster scenarios and running through mobilization procedures. These exercises reveal gaps — in equipment, in training, in interagency coordination — that can be addressed before the next real event.
Family Assistance
Mass casualty events create a secondary crisis: families seeking information about missing loved ones. The coroner’s office is responsible for establishing family assistance centers where relatives can report missing persons, provide antemortem identification data, and receive death notifications.
These centers are staffed with investigators, counselors, and administrative personnel. Families provide photographs, dental records, descriptions of tattoos and scars, medical history, and DNA reference samples. The process is agonizing for the families and draining for the staff.
The notification process follows strict protocols. A positive identification must be confirmed before a family is notified. False positives — telling a family their loved one has been identified when the identification is wrong — are considered the worst possible error. The office would rather delay notification than make a mistake.
The Permanent State of Readiness
Los Angeles does not get to choose when the next disaster will happen. The city sits on fault lines. It is surrounded by fire-prone wildland. It hosts one of the busiest airports in the world. Its freeways carry millions of vehicles daily. Its population density guarantees that any disaster will produce casualties.
The coroner’s office exists in a permanent state of readiness — maintaining plans, training personnel, stockpiling supplies, and coordinating with the dozens of agencies that would be involved in a mass fatality response. It is preparation for an event that everyone hopes will not come and that history guarantees will.
When it does, the office will do what it has always done: process the dead with accuracy and dignity, identify them, return them to their families, and document what happened so that the living can learn from it.
