WORTH 100 POINTS HELP ASAP PLEASE IT'S DUE VERY SOON Estimate the time since death (TSD), using the information provided. Work in pairs. Assume normal temperatures and environment, unless otherwise noted. You can type in the text box, or upload your answers.

1. The body is warm to the touch. No rigor is noticeable. A small level of livor is present, but blanches. Therefore, the body has not been dead for more than hours.

2. The body is warm and beginning to show signs of stiffness. The body has been dead between and hours, approximately.

3. The body is cold to the touch and stiff. The body has been dead between and hours, approximately.

4. The body is cold and not stiff. The body has been dead for more than hours.

5. Once a body has been in place for some time, even 30 minutes, some hint of fixed lividity may be apparent. If any fixed lividity shows up on any surface other than the inferior one, it is an indication that at some time thirty minutes or so after death the body was moved. a) A body found with heavy fixed lividity on the upper surfaces and light but fixed lividity on the lower surfaces was moved after hour(s) and has been in place for hour(s) or more. b) A body found with equal degrees of lividity on the upper and lower surfaces was repositioned or rolled over after hours.

6. The jaw and neck are rigid but the rest of the body is limp, indicating the body has been dead for to hours.

7. Every skeletal muscle is rigid down to the legs (but not including the legs) means the body has been dead for hours.

8. The jaw is limp but from the neck down is rigid, so the time since death is approximately hours.

9. In true algor mortis in a normal environment, the body decreases temperature 2 degrees per hour in the first 6 hours, and 1.5 degrees per hour from 6 to 12 hours. Therefore, if the liver (organ) temperature was 89 degrees, the person has been dead for approximately hours. What if the liver temperature is 84 degrees? Time since death would be hours.

10. Scenario 1: Only the legs are in rigor. The body is room temperature. Livor is fixed on the lower side. The person has to have been dead for at least hours.

11. Scenario 2: A woman is found with some light lividity on her front side and heavy lividity on her back side. Her roommate claims that he found her in the apartment after coming home from work and, attempting life-saving techniques on her, may have turned her over in the process. Once he could not revive her, he left her in place for a couple of hours, claiming he was too scared to call the police, who arrived within half an hour after his call. Do you buy his story? Why or why not?

12. A body is found outside in cold weather. The body itself is cold and only the legs are stiff. The body has been dead between hours.

13. A body is found in a car at the end of Southern Blvd. during the summer. The windows to the car are closed. It is bloated, with marbling and dark discoloration. The body has probably been dead for at least days.

14. A badly decomposed, almost skeletonized body is found on the mesa in May. Some flesh is still present on the bones, but some of it has mummified. Why is it so difficult to estimate this person’s TSD?
