Death+Notes+CK


 * //Time of Death Estimation//**

-24hrs to 36 hrs
 * 1.** Rigor Mortis-> after death muscles relax and them become rigid

Factors Affecting RM: 1. Ambient Temperature 2. Weight/Size 3. the type of clothing they are wearing 4. Illness 5. level of physical activity 6. sun exposure

when the heart stops pumping blood, blood begins to settle in the parts of the body closest to the ground -lividity->pooling of blood in the body -*helps determine if body has been moved -starts almost immediately and continues for about 12 hours
 * 2** Livor Mortis-> (blood)

-process by which the body temperature continually cools after death until it reaches room temperature -begins ~1 hour after death; body loses heat ~1-1.5 degrees Fahrenheit per hour -thermometer inserted into the liver factors affecting: 1. location 2. weight/size 3. clothing 4. weather 5. activities
 * 3** Algor Mortis ->Body temperature

Time of Death Estimation Step by Step

1. Mortis 2. Determination of K levels in ocular fluid surrounding eye 3. amount of food in stomach ->takes ~24 hrs for undigested food to release from large intestine after eating (stomach and small intestine + large intestine empty) ->stomach empty, food in small intestine, 4-6 hours since their last meal ->undigested stomach contents, 0-2 hours after last meal

->identify specific insects present on the body, examine the stage of development of fly larva and back calculate time of death ->blowflies are 1st to infest the body -they lay eggs -those eggs turn into maggots -maggots are what consumes the tissue
 * 4** Forensic Entomology-scientific study of insects and their relation to criminal investigation
