Estimating Time Since Death Part I: Using Algor Mortis After death, the human body no longer generates warmth and as a result, it begins to cool down. This phenomenon is known as Algor Mortis or the cooling of the body after death. Forensic documentation and experimental studies have shown that the body cools at a predictable rate. The body will cool until it reaches the temperature of the environment it is in. Normal body temperature is 98.6°F (37°C). Use the information provided to calculate answers to the following questions. et Celsius Fahrenheit Timing (per hour) (per hour) Cooling within the first 12 hours after death 0.78° 1.4° Cooling 12 hours after death - 0.39° 0.7° 1. Plot the following body temperature measurements taken at 30 minute intervals on a murder victim. Using your graph, estimate the time of death by drawing a line through the data and determining at what time the body was at 37 degrees Celsius. Assume a fairly even rate of temperature drop. — Time of Measurement Temperature in Celsius — 7:00am 32.5 7:30am 31.8 8:00am 31.2 8:30am 30.5 9:00am 29.9 9:30am ; 29.3 3°. 30 00v1
