A METHOD OF MEASURING THE POSTMORTEM INTERVAL USING THE CHANGES IN THE WATER CONTENT OF LEAKED BLOOD

摘要

The present invention relates to a method for estimating the postmortem interval based on the amount of moisture in leaked blood comprising: a step of measuring the weight of moisture evaporated from leaked blood by measuring the weight variation of the blood taken in the field according to time (ST-110); a step of outputting the specific data of the dead by deducting the ratio between the specific moisture of the dead and residues using the blood taken from the body (ST-120); a step of deducting an equation for estimating the postmortem interval by substituting the weight measured using the blood taken in the field and the ratio measured from the blood of the body (ST-130); and a step of substituting the deducted postmortem interval for an error range (ST-140). The present invention can objectively and accurately estimate the time of death and can estimate the time of death from the weight variation of the blood according to time, thereby taking a blood sample without additional precise equipment or regardless of the skilled level of experimenters. Thus, the present invention can make data for conveniently estimating the time of death.
