FOR 106 – Biology behind the Crime SceneSpring 2021Lab # 4 Death Investigation (Forensic Pathology)This is an ONLINE ASSIGNMENT, and it must be submitted through CanvasIt is due Tuesday February 9that 11:59 pmAdapted from Forensic Science: Fundamentals and Investigations 2012 Update.Anthony J. BertinoForensic Science: An Introduction to Scientific and Investigative Techniques; 2014; S. H. James, J. J. Nordby, S. BellBody Examination and Forensic PathologyINTRODUCTIONA central player in modern death investigation is themedical examiner,a medical doctor1who studies anddiagnoses disease in humans and studies trauma that leads to the death of an individual. The forensicpathologist could be considered as medical examiners and in charge of the pathological and toxicologicalexamination of tissues and organs. The examination of human death involves two groups of experts. Forensicscientists investigate all the circumstances of the crime from the surface of the body outwards, and forensicpathologists who study the body from the skin inwards.Autopsymeans to look at oneself, so this term hardly seems appropriate for the examination of a dead body. Amore technically correct term for the dissection isnecropsy,or looking at the dead. The term “autopsy” involvesstandardized dissection of a corpse to determine cause, manner and mechanism of death.It remains difficult to precisely pinpoint the moment that someone dies. For one thing, death is a process ratherthan an instant event. The moment of death is usually considered the point of no return. One definition ofdeathis the cessation, or end, of life. To be more precise, death is sometimes defined as the “irreversible cessation ofcirculation of blood”. Death might also be defined as the cessation of all brain activity. Experts cannot agree on asingle definition for death!The manner, cause and mechanism of deathThere are five ways a person can die, referred to in official terms as themanner of death:-Natural death: caused by interruption and failure of body functions resulting from age ordisease. This is the most common manner of death.-Accidental death: caused by unplanned events, such as a car accident or falling from a ladder.-Suicidal death: occurs when a person purposefully kills oneself, whether by hanging, drugoverdose, gunshot, or some other method.-Homicidal death: the death of one person caused by another person.-Undetermined deathThe reason someone dies is called thecause of death. The forensic/medicolegal examination. More commonare:1.Blunt force trauma, refers to injuries caused by dull or non-sharpened objectsa.Blunt objects produce lacerations, or tears in the tissue.b.Blunt trauma commonly causes death from brain contusion or accumulation of blood in thetissues outside the normal blood vessels.
