Q1. Human remains were found in a temperate region in early fall. The remains resemble a woman who has been missing for two weeks. Her internal body temperature was measured as 24°C at the crime scene. Assuming a normal body temperature of 37°C and a 3-hour temperature plateau, it is likely that this woman died: A. Fewer than 6 hours ago B. About 16 hours ago C. About 36 hours ago D. About 48 hours ago - Answer-B. About 16 hours ago Q2. A body exhibits full rigor and maximum lividity. Assuming a mean time of development for both, what is the estimated PMI? A. 8-10 hours ago B. 30-40 hours ago C. 40-48 hours ago - Answer-A. 8-10 hours ago Q3. Human remains were found exposed outside in the middle of a wooded region. Forensic anthropologists determine that there is no joint stiffness, livor mortis has reached maximum lividity, and the body temperature has reached ambient conditions. The time since death is: A. Fewer than 2 hours ago B. Fewer than 12 hours ago C. Between 24 and 48 hours ago - Answer-C. Between 24 and 48 hours ago Q4. Based on the information in this image and the decomposition stages presented in Table 3, what stage of decomposition is this pig in? A. Fresh (no evidence of autolysis or putrefaction) B. Pre-bloating (minor changes due to putrefaction but no abdominal bloating) C. Bloating (abdomen bloated, discoloration spreading but still light in color) D. Advanced Decomposition (putrefaction evident throughout the body) - Answer-C. Bloating (abdomen bloated, discoloration spreading but still light in color) Q5. A corpse was found with blowfly PUPAE (pupal stage) around the mouth, ears, and nose. Using the blowfly life cycle figure presented above (Figure 34), determine the number of hours ago the person died. Remember you have to add all of the transition times for previous stages (23+27+...etc.) until you reach the stage of the life cycle you observe on the corpse.
