You have been dispatched to the scene of a homicide where a body was discovered in a field. The victim appears to have been shot several times and then burned. The identity of the deceased is in question, and the lead detective asks you whether DNA would be useful in this case to determine the identity of the deceased.
The use of DNA analysis is critical for this investigation because, in situations of extreme fire impact, only bones and teeth are available for examination. In such a case, post-mortem computed tomography (CT) is highly useful in finding features of such a body. While a medical examiner must conduct this process, the DNA recovery must occur at the crime scene to avoid further tampering with the evidence. If the suspected burnt person has parents or children, these relatives offer the best option for identification.
