DEATH+CHAPTER-LR+&+SF

Page 17&18 Short Answers 1A. They both have to deal with not existing anymore. Another difference is that the cause of death is when someone dies, manner of death is the way(s) a person can die. The cause of death describes the events that lead to the cause of a person's death. The mannor of death definition is one of four means by which dies. Natural, Accidential, Sucidial, or Homosidial. 1B. The cause of death describes the event(s) that lead to a person's death. For example hanging in a nuse. The meckonism of death describes the "specific" change in the body that brought about the "cessation" of life. If the cause of death is a stroke for example, the meckonigism might be blood clot to the heart. The meckognism of death's definition is the specific body failure that leads to death. 1C. Larva's definition is immature form of an animal that undergoes metamorphisis. When you die, the ivestigators can tell how long ago you died based on the stage that the larva is at one your body. Pupa- the state in an insectslife cycle when the larva forms a capsul around its self and changes into its adult form. Again the investigators can figure out when you died by dating the stage of the insects in their life cycle. 1D. Rigor mortis- is when a death occursthe body gets a stiffness Its temporary and the investigators can determine the time of death by looking at the body. This starts within 2 hours after the death, starts in the head and works its way down to end of the body. Livor Mortis- happens right after you die, and its when the mucles relax. It means that the body is beginning to decompose. 2. This can be described as a stage of decomposition. After 4 days of being dead, the abdomine will swell with gases of carbon dioxide that is released from the intestines. Its on its way to bursting. So you could just tell your friend that it has been dead for 4 days. 3. Enviornmential condiations can effect the way that a body decomposes. Based on the body temperature, and the fact that less insects would be located on it since it had been moved. Liver Mortis is another way to show that it had been moved. Based on the stiffness of the body, its an easy sign to see if anything has been moved or not. 4. It must have died within 12 hours previous of being discovered by the person. Liver Mortis begins in the head and the neck and moves down to the end of the body. Then the body begins to loosen up again due to Rigor Mortis. If its over 12 hours of dead the body is in the stage of Rigor Mortis, and if its under 12 hours of being dead, then the body is in Liver Mortis. 5. Forensic entomologist can determine when the blowflies arrive on the body by studying the insects on the corps. They are attracted to two gasses of decomposition, they are Putresine and Cadaverene. These are two gasses that are leaked out of the boeies. Moist or warm areas, and openings of the body, like mouth, ears, nose.....Insects can not determine the time of death, but they can give the investigators a rough estimate. Blowflies are the first insects to arrive at the scene tiny wasps come to lay their eggs. The cheese skippers arrive also. The last group to arrive are those that favor drier conditions on the body. These insects might be mites and beatles. They feed on the dry skin and hair particles.
