Suspense Radio

Bestselling Author and forensic expert D.P. Lyle hosts the show. The ME’s 3 most important determinations: Cause, Manner, and Time of Death Part I: Cause and Manner of Death Notes CAUSE/MECHANISM OF DEATH: Cause of death is why the individual died Heart attack, GSW, traumatic brain injury, diseases Mechanism-physiological derangement that causes death One cause—several mechanisms Example: MI-arrhythmia, cardiogenic shock, rupture Example: GSW—heart or brain damage, exsanguination. wound infection One mechanism—several causes Example: Exsanguination—GSW, ulcer, meds, disease Just as a cause of death can lead to many different mechanisms of death, any cause of death can have several different manners of death. A gunshot wound to the head can’t be a natural death, but it could be deemed homicidal, suicidal, or accidental. MANNERS OF DEATH: For what purpose and by whose hand NATURAL: Natural deaths are due to the workings of Mother Nature in that death results from a natural disease process. Heart attacks, cancers, pneumonia, and strokes are common natural causes of death. This is by far the largest category of death that the ME sees. ACCIDENTAL: Accidental deaths result from an unplanned and unforeseeable sequence of events. Falls, automobile accidents, and in-home electrocutions are examples of accidental deaths. SUICIDAL: Suicides are deaths that come by the person’s own hand. Intentional self-inflicted gunshots, drug overdoses, or self-hangings are suicidal deaths. HOMICIDAL: Homicides are deaths that occur by the hand of another. Note that a homicide is not necessarily a murder. Homicide is a determination of the ME; murder is a legal charge that is determined by the courts. Though each would be ruled a homicide by the ME, the legal jeopardy is much different for a court verdict of negligent homicide as opposed to first- or second-degree murder. UNDETERMINED OR UNCLASSIFIED: This extra category is used in situations where the coroner can’t accurately determine the appropriate category. Examples: Car/pedestrian Heroin/Drug OD GSW Psychological Autopsy Manner determines whether there is an investigation Manner not fixed—can change Proximate cause—cascade of events
