Asian tsunami victim identification
Asian tsunami victim identification refers to the extensive efforts made to identify the remains of individuals who perished in the catastrophic tsunamis triggered by a massive earthquake on December 26, 2004. This disaster, one of the deadliest in modern history, claimed approximately 250,000 lives across several countries bordering the Indian Ocean, affecting both local residents and foreign tourists. The task of identifying victims was incredibly challenging due to the rapid decomposition of bodies and the lack of forensic resources in the affected regions.
To address these challenges, a multinational Disaster Victim Identification (DVI) center was established in Phuket, Thailand, which brought together forensic experts from thirty countries. Identification methods primarily relied on dental records, fingerprint analysis, and DNA testing, with dental records proving particularly effective for non-Thai victims. Despite significant progress, a substantial number of bodies remained unidentified one year after the disaster, prompting the establishment of a cemetery for the unidentified remains, particularly for migrants.
Overall, the collaborative international response to victim identification highlighted the importance of forensic science in addressing the aftermath of natural disasters, while also revealing the disparities in resources available for different populations.
Asian tsunami victim identification
DATE: Tsunamis struck on December 26, 2004
THE EVENT: An earthquake measuring 9.3 on the Richter scale triggered tsunamis that devastated the coastlines of several Asian countries. One of the worst mass-casualty disasters in history, the tsunamis killed as many as 250,000 people, including Asians living in coastal communities and many tourists from Western nations.
SIGNIFICANCE: The Asian tsunamis of 2004 presented one of the biggest challenges ever faced by forensic teams in identifying the bodies of massive numbers of victims of a natural disaster. The identification effort drew experts from thirty different nations and produced successful collaboration among them.
On December 26, 2004, a massive earthquake struck in the ocean near the west coast of Sumatra, Indonesia, and triggered a series of deadly tsunamis. It has been estimated that up to 250,000 people became tsunami victims along the coasts of many countries bordering the Indian Ocean; victims included the citizens of eleven countries, many of them tourists who were spending time at Asian resorts. An estimated two million people lost their homes, and thousands were reported missing. The magnitude of the tragedy was unprecedented, and it created an unprecedented challenge for the forensic teams that came together to identify the dead.
The Disaster Victim Identification Center
Following the tsunamis, many bereaved families sought assistance in identifying the dead. Despite their pleas for help, the rate at which the bodies were decomposing caused concerns about epidemics and forced local communities and national authorities to sanction mass burials without identification of the bodies. Many Western states, however, exerted every effort to ensure that their citizens who had died were identified before their remains were interred or cremated.
The challenges of identifying victims after the tsunami were daunting. High temperatures accelerated the rate of of the bodies, and the bloating and discoloration of faces made visual identification almost impossible after two days. Refrigeration was not immediately available to preserve the remains. In addition, no single country among those affected had sufficient forensic capacity to identify thousands of victims. Lack of national and local plans for mass fatalities further limited the quality and timeliness of the response, as did the absence of practical field guidelines or an international agency to provide technical support.
To respond to the problem of victim identification, Thai authorities set up a multinational disaster victim identification (DVI) center in Phuket, Thailand. The center drew the participation of three hundred investigators from thirty countries. Many of these investigators had expertise in DVI, having worked on teams that had identified mass fatalities from wars, natural disasters, and terrorist attacks.
The global effort to identify the victims of the tsunamis involved the participation of private corporations as well as individuals. Kenyon International Emergency Services, for example, conducted operations and eventually handed over a state-of-the-art identification tool kit worth ten million dollars to the Royal Thai Police’s Thai Tsunami Victim Identification (TTVI) unit. Kenyon fielded more than one hundred employees to help create and run a comprehensive forensics database for use by analysts and Interpol experts who worked at the TTVI center in Phuket.
Identification of the tsunami victims was extremely difficult because many bodies recovered from the sea were badly decomposed. The scientists made positive identifications by analyzing dental records, fingerprints, or DNA (deoxyribonucleic acid); relatives of the deceased provided DNA samples and information that helped identify the bodies.
The Information Management Center at the DVI center processed several types of data, including postmortem data collected during victim examinations conducted in temporary morgues and antemortem data on possible victims gathered from the numerous countries involved. These data were entered into the PlassData system under standard operating procedures laid out by the Interpol Disaster Identification Manual. When the scientists were able to match dental, fingerprint, or DNA records with a body, they presented their findings to the Thai Reconciliation Commission, which, if satisfied, authorized the issuance of a Thai death certificate.
Dental Records
The identification of tsunami victims through the use of dental information (forensic odontology) proved to be highly efficient, reliable, and fast. This method of victim identification, however, favored nationals of Western states, who typically had dental records that helped in the identification process. Dental data were generally unavailable for the Thai population, so this method led to the identification of only a small number of Thai victims. In contrast, for non-Thai, victims the successful identification rate using dental data was about 80 percent.
Antemortem dental treatment data include X-rays and treatment records, as well as plaster models. In most cases, reliable identification of bodies using dental data depends on the availability of recent, high-quality data. If the dental data are scarce or old, investigators must utilize all available methods of identification and the assistance of experienced forensic odontologists to achieve reliable results. In the case of the tsunami victims, this was the case especially for children and adolescents, who had very little or no dental treatment.
The reliability of dental records as a means of identification became evident early in the work with tsunami victims. After the first three months, 88 percent of the successful identifications of victims had been accomplished with the help of dental data. The large majority of those successfully identified were non-Thai victims.
Unidentified Bodies
One year after the tsunamis struck, the TTVI center had identified all but 805 of the 3,750 bodies it had received for analysis. About 45 percent of the identifications had been made through dental records, 35 percent through fingerprint analysis, and the remaining 20 percent through DNA analysis. The remaining unidentified bodies were kept in refrigerated containers as efforts to identify them continued. Many of the unidentified were believed to be illegal immigrants, which could explain why their relatives were reluctant to claim them. One year after the tragedy, 160 non-Thais and 548 Thais remained missing.
Two years after the tsunamis, Thailand opened a cemetery for the last of the unidentified victims, about 400 bodies. The remains, mostly those of Burmese migrants, were buried in identical aluminum coffins. The graves are marked with concrete headstones that include registration numbers that will allow authorities to exhume the correct bodies if identifications are made in the future through the use of DNA samples taken from the bodies before burial.
