Rain opened the month of June this year. For those who were affected in previous years’ typhoons and who are still recovering from the aftermath, continuous strong rain brings back memories of loss of lives and properties in affected areas. Moreover, many survivors realize in a vivid way their total helplessness against an environment we have forgotten to protect. In 2011 for example, Typhoon Sendong caught the entire Philippines by surprise. The entire nation was shocked when it realized the extent of the damage and the large number of people that remain missing. Not used to typhoons and harsh weather, the cities of Iligan and Cagayan de Oro had to grapple with problems they had never encountered before. Both cities had to weigh their priorities and manage their resources to more effectively aid the communities that were most affected. In order to assist in the post-disaster effort, the University of the Philippines established “UP Padayon” and sent a multidisciplinary team composed of medical doctors, dentists, geologists, public health personnel, forensic pathologists and forensic DNA scientists to Iligan City several days after the flood. The forensic group tasked with specifically helping in the identification of recovered remains discovered the need for a more efficient system for disaster victim identification (DVI) when handling a disaster of such a magnitude.

 But why identify the dead? Many people including policy-makers have posited — should we not allocate resources for the living and bury the dead, even if unidentified? The identification of the dead is a complex and potentially expensive task especially when all the necessary information is not documented before body decomposition sets in. Why then should we identify the dead when they are dead? There were several reasons that were provided. These included 1) the need to investigate if the death was caused by a criminal act or a natural calamity; 2) the planned re-marriage of the living spouse; 3) financial reasons particularly in the payment of pensions, insurance and other death benefits to the deceased’s family; 4) proper burial following the traditional belief of the family; and 5) the need to provide proper closure for relatives of a missing person. Simply stated, the identification of the dead is not for the sake of the dead, but for the sake of the living.

In recent times, the changing climate appears to bring more damage to properties and a greater loss of lives. Addressing the cause of climate change is important to prevent such losses. However, we also need to manage the effect of severe typhoons and to give importance to helping communities to move forward as quickly as possible. Part of the rehabilitation process is an efficient DVI strategy. DVI is a complex task with three primary means for identification: fingerprint analysis, dental examination, and DNA typing. Information about the external appearance of the recovered remains and other secondary but distinguishing features are useful in the process (http://www.interpol.int/ INTERPOL-expertise/Forensics/DVI). DVI teams work in an interdisciplinary manner and engage the services of experts in various fields, as needed. One major step in DVI is the establishment of a missing person database that serves as the repository of information of all material about missing persons after a disaster.

Fingerprint analysis is useful when bodies are not severely decomposed. Moreover, fingerprint and dental records taken ante-mortem should be available for comparison with the same data obtained from recovered remains. In contrast, DNA profiling may be used even after the start of decomposition and in the absence of ante-mortem data. The selection of the appropriate method for human DNA profiling relies on the condition of the recovered sample for DNA typing and the availability of reference samples, e.g. from family members and relatives, needed for genetic comparison.
