...investigation info, from the following site: http://faculty.ncwc.edu/toconnor/315/315lect10.htm ESTIMATING THE TIME OF DEATH There's always going to be at least two (2) estimates of the time of death -- the police department's official estimate (which may or may not be yours) and the Medical Examiner's estimate. Legally, you should be within 4 hours of being accurate, but this is a tough standard even for the best coroners. Remember that, after death, the body starts to cool down to whatever the outside (or room) temperature is. At death, the body starts to drop from it's normal 98.6 degrees by a factor of 3 degrees the first hour and a factor of 1 degree each subsequent hour. Then, after 30 hours, it starts to go up again because of the heat generated by decomposition (but this varies by room or outside temperature, so you need to know weather conditions). The following table illustrates: 98.6 - time of death 95.6 - one hour after death 94.6 - two hours after death 93.6 - three hours after death 92.6 - four hours after death 91.6 - five hours after death 90.6 - six hours after death -------- (to room or outside temp.) 66.6 - thirty hours after death 67.6 - thirty-one hours after death 68.6 - thirty-two hours after death 69.6 - thirty-three hours after death -------- (to room or outside temp.) Rigor mortis is also something you should know about. The body is limp until about 5-6 hours after death, then a hardness begins to set in around the jaw area in front of the ear (temporal mandibular joint area). It then spreads throughout the body for a period of time, and then the body goes limp again. The following chart illustrates: stiffness in jaw -- 6 hours after death stiffness in upper torso -- 12 hours after death stiffness in whole body -- 18 hours after death limpness returns to body -- 36 hours after death Most Serious Stressors (related to committing murder or suicide) 1. Death of spouse 2. Divorce 3. Marital difficulties 4. Trouble with the law 5. Death of friend or family 6. Serious illness or disease 7. Fired at work 8. Retirement Hmmmm...Raven was affected by 4 of the 8 things above... yikes! Last, but not least, something my police and detective/investigator friends have always maintained: With homicides, a good rule to follow is make the arrest within 72 hours or the chances of ever making it plummet (Morn 2000).
