1. Chapter 11

2.  Brain death  End of blood circulation  Autolysis (Fig. 11-1 from book removed)

3.  “Manner of Death”  Natural death  Accidental death  Suicidal death  Homicidal death

5.  Cause of Death  Describes events leading to death  Examples: stroke, drowning, shooting, etc.  Mechanism of Death  Specific change in body that brought about death  Examples: loss of blood, pulmonary arrest, etc.  Often single statement  “Massive trauma to body leading to pulmonary arrest”

6.  Lividity – Pooling of blood in the body  Appears two hours after death  Permanent after eight hours  Process is faster in hotter temperatures  Livor Mortis – “Death Color”  (Fig. 11-4 from book removed)  Has the body been moved?

7.  Rigor mortis – “Death stiffness”  Starts within 2 hours  Most rigid at 12 hours  Gradually disappears after 36 hours (Fig. 11-5 from book removed)

8.  Rigor mortis is affected by:  Temperature (cooler takes longer)  A person’s weight (fatter takes longer)  Type of clothing  Illness  Level of physical activity shortly before death (faster after exercise)  Sun exposure

9.  Algor mortis – “Death heat”  Temperature loss  About 1 degree F or 0.78 degrees C per hour  Slowed by weight, clothing, or hot environments  Temperature determined by thermometer in liver

10.  Forensic entomology  Insect stages:  Egg  Larva (instar)  Pupa  Adult

11.  Factors affecting insect development  Temperature  Wind  Time of day  Season  Exposure to elements  Estimation of time of death obtained by raising insects from scene in same conditions at lab.  Process is known as Accumulated Degree Hours (ADH)
