Abstract: The 2009 Victorian Bushfires Disaster started on a record hot day in February 2009 and resulted in over 300 separate fires with a death toll of 173 and over 400 presentations to hospital emergency departments. This occurred a little over a week after a heat wave in which over 400 people were thought to have died prematurely in southeastern Australia. The Victorian Institute of Forensic Medicine in collaboration with the police force and the State Coroner''s Office and over 100 colleagues from all over Australia, Indonesia, New Zealand and Japan implemented a DVI process based on Interpol guidelines to identify the deceased persons. CT scanning was conducted on all remains collected and played a pivotal role in the identification processes in conjunction with experts in pathology, anthropology, forensic odontology and molecular biology. This paper outlines the scale of the disaster and the work, from a forensic medical perspective, to identify the deceased. [Copyright &y& Elsevier]

Abstract: The February 7th 2009 bushfires in Victoria, Australia, resulted in the deaths of 173 individuals, of whom 164 were included in the subsequent DVI operation. The final stage of the International DVI protocol is a debrief, referred to as Phase 5. The Phase 5 operational debrief process conducted in the wake of this disaster was designed for the purpose of developing new strategies in light of this experience. The agencies involved included the Coroners Court of Victoria, the Victorian Institute of Forensic Medicine, the Department of Justice, and Victoria Police. During the course of this debriefing process strategies and protocols were developed which aim to improve the capacity of all agencies to respond and resolve future incidents. This paper outlines the Phase 5 debrief carried out in the 6 months following the final coronial identification board, and details the findings and recommendations made by the agencies involved.

Abstract: CT scanning of the deceased is an established technique performed on all individuals admitted to VIFM over the last 5 years. It is used primarily to assist pathologists in determining cause and manner of death but is also invaluable for identification of unknown deceased individuals where traditional methods are not possible. Based on this experience, CT scanning was incorporated into phase 2 of the Institute''s DVI process for the 2009 Victorian bushfires. All deceased individuals and fragmented remains admitted to the mortuary were CT scanned in their body bags using established protocols. Images were reviewed by 2 teams of 2 radiologists experienced in forensic imaging and the findings transcribed onto a data sheet constructed specifically for the DVI exercise. The contents of 255 body bags were examined in the 28 days following the fires. 164 missing persons were included in the DVI process with 163 deceased individuals eventually identified. CT contributed to this identification in 161 persons. In 2 cases, radiologists were unable to recognize commingled remains. CT was utilized in the initial triage of each bag''s contents. If radiological evaluation determined that bodies were incomplete then this information was provided to search teams who revisited the scenes of death. CT was helpful in differentiation of human from non-human remains in 8 bags, recognition of human/animal commingling in 10 bags and human commingling in 6 bags. In 61% of cases gender was able to be determined on CT using a novel technique of genitalia detection and in all but 2 cases this was correct. Age range was able to be determined on CT in 94% with an accuracy of 76%. Specific identification features detected on CT included the presence of disease (14 disease entities in 13 cases), medical devices (26 devices in 19 cases) and 274 everyday metallic items associated with the remains of 135 individuals. CT scanning provided useful information prior to autopsy by flagging likely findings including the presence of non-human remains, at the time of autopsy by assisting in the localization of identifying features in heavily disfigured bodies, and after autopsy by retrospective review of images for clarification of issues that arose at the time of pathologist case review. In view of the success of CT scanning in this mass disaster, DVI administrators should explore the incorporation of CT services into their disaster plans. [Copyright &y& Elsevier]
