Determining the death time

Death time

One of the interesting topics that constitute the basic core of forensic medicine and that must be addressed is determining the time of death or the interval between the time of death and the time of finding the body (that is, the period following death), which often represents the most difficult and most accurate stage performed by the forensic doctor. .

As long as there is no witness to the death, or the time has passed since the accident, the exact time of death cannot be determined. The longer the time since death occurred, the greater the chance of misidentifying the postmortem interval.

There are several individual observations that can be used together to provide the best estimate of time of death. They include:

1-Thermal drop rate: the temperature decreases by one degree every hour during the first 8 hours after death, then by one degree every hour and a half to two hours during the next 16 hours for the first 8 hours (8_24 hours), so that the body temperature becomes equivalent to the ambient temperature after 24 hours .

2-Throwing cyanosis: It goes through three stages: stagnation, penetration, and absorption. For this, we use a special device with a weight of (2 kg/cm2) that applies pressure on the corpse and then raise it to monitor the time required for the color to return.

3-Throwing rigidity (muscular rigidity): a phenomenon that affects all the muscles of the body and is characterized by their contraction, stiffness and stability in one position. Immediately after death, the muscles relax, but after about two hours the rigidity begins from the top to the bottom, as the first muscles to get rigid are the muscles of the face, neck, then the trunk, then The upper and then lower ends. It takes 12 hours to cover the entire body.

4-Decay (rotting): It is a phenomenon in which the decomposition of organs and tissues occurs by the action of aerobic and anaerobic bacteria. This process begins immediately after death, but its manifestations take several hours, as a green spot appears on the abdomen at the end of the first 24 hours, to be the first sign of the decomposition process.

5-Emptying the stomach and the digestive system: The stomach empties its content within (3-6) hours after the last meal, and it may contain toxic or alcoholic substances that are responsible for death after eating, so it is important to open the stomach to monitor and detect food, and if it is present, it is Significant evidence that death occurred 6 hours ago.

6-Chemical changes of body fluids and parameters of the scene of death are also important and essential factors for estimating the time of death.
