__**Activity 11-1**__

1. The body has been dead either 0-2 hours or more than 48 hours. 2. The body has been dead about 12 hours. 3. The body has been dead 2-6 hours. 4. The body has been head 15-36 hours. 5. The body has been dead about 2 hours. 6. The body has been dead 36-48 hours (because the rigor left all places except for his arms)
 * Part A**

7. The woman has been dead less than 15-36 hours. This is the time frame under normal conditions that the rigor begins to go away, and it leaves the face and neck first. But since the woman is thin and it was warm outside, the speed of the rigor is accelerated (by both of these conditions). 8. The man has been dead a little more than 12 hours, because the slower temperature slows down the rigor a bit. 9. The man has probably been dead a good amount of time after 6 hours because he was both obese and it was cold in the room. Both of these factors slow down the rigor mortis process. 10. The woman has been dead less than 15-36 hours. The rigor mortis process was accelerated because she was exercising before she was killed and she was kept in a warmer atmosphere (the car) after death. 11. Under normal conditions the body has either been dead 0-2 hours, before the rigor started, or has been dead more than 48 hours, after the rigor is gone. 12. Under normal conditions, the body has been dead 12 hours, because this is the time where peak rigor is exhibited. 13. If the body is completely rigid, he has been dead over 12 hours. Since he was in a really cold temperature it would take longer than the original 12 hours that it takes to reach peak rigor. 14. The woman has been dead less than 15-36 hours. 15-36 hours is the time for this type of rigor under normal conditions, but exercise and a warm temperature both accelerate the rigor mortis process.

 * Activity 11-2**

1. How long has body been dead? 37 (temperature of a normal body) – 33.1 (temperature of dead body)= 3.9 degrees Celsius - So, dead less than 12 hrs (0.78)(# of hrs) = 3.9 degrees Celsius Solve equation- # of hrs= **5 hrs**
 * Part A**

2. The body has been dead for a shorter amount of time than in problem 1, because it was in a colder temperature, in which the body temperature decreases faster.

3. 37- 25.9 = 11.1 degrees Celsius - so longer than 12 hours 11.1- 9.36= 1.74 degrees Celsius lost after the first 12 hours (0.39)(# of hours) = 1.74 12 + 4.46 = **16.46 hours dead**
 * 1) of hours = 4.46 hours

4. 37-15.6 = 21.4 degrees Celsius (longer than 12 hours) 21.4 – 9.36 = 12.04 degrees Celsius lost after the first 12 hours (0.39)(# of hours) = 12.04 12+ 30.87 = **42.87 hours dead**
 * 1) of hours = 30.87 hours

5. 37-10 = 27 degrees Celsius 27-9.36 = 17.64 degrees Celsius lost after the first 12 hours (0.39)(# of hours) = 17.64 12 + 45.23 = **57.23 hours dead**
 * 1) of hours = 45.23 hours

6. 37- 29.4 = 7.6 degrees Celsius (0.78) (# of hours) = 7.6
 * 1) of hours = **9.74 hours dead**

7. 37-24 = 13 degrees Celsius 13- 9.36 = 3.64 degrees Celsius lost after the first 12 hours (0.39) (# of hours) = 3.64
 * 1) of hours = **9.3 hours dead**

1. Reduce 10-hour estimate 2. Reduce 3. Increase 4. Reduce
