which is the best way to know that when do the decedent die?

Question

i mean... when a person die for a long time, which is the best way to know how long he die?

Answer 1

huh?

Answer 2

The best way to know when a decedent died is the termination of respiration (heartbeat and breathing). If the question is what to do when a decedent dies, then that depends on the situation. If you are alone with the decedent, call 911. If you need to know what to do as far as funeral, burial, cremation, legal and financial matters, start with a funeral director and then consult with an attorney.

Answer 3

Determining time of death
The time of death is a critical piece of information for investigators attempting to understand the cause of suspicious deaths.

Temperature
The temperature of a body can be used to estimate time of death during the first 24 hours. Core temperature falls gradually with time since death, and depends on body mass, fat distribution and ambient temperature. If the body is discovered before the body temperature has come into equilibrium with the ambient temperature, forensic scientists can estimate the time of death by measuring core temperature of the body.

Rigor mortis
The presence of rigor mortis also assists forensic scientists in determining the time of death. The body muscles will normally be in a relaxed state for the first three hours after death, stiffening between 3 hours and 36 hours, and then becoming relaxed again. However, there is considerable uncertainty in estimates derived from rigor mortis, because the time of onset is highly dependent on the amount of work the muscles had done immediately before death.

Insects
The presence of insects in a corpse is a critical clue towards estimating the time of death for bodies dead for longer periods of time. Because flies rapidly discover a body and their development times are predictable under particular environmental conditions, the time of death can be calculated by counting back the days from the state of development of insects living on the corpse.

For example, if a body was found in an air-conditioned building (21°C) with second instar larvae (stage of development between moulting) of Lucilia sericata feeding on the corpse, a forensic entomologist could calculate that those larvae had moulted from their first instar sometime in the last 12 hours. Because the eggs take 18 hours to hatch and the first instar takes 20 hours to develop, the most recent time the eggs could have been laid was 38 hours earlier, if the larvae had just moulted. If they were old larvae, about to moult into their third instar, the most recent time of death would be 50 hours prior to discovery of the body.

Usually, time determinations would not be so easy because weather conditions are more variable, and identification of most maggots to species level is difficult. Forensic scientists usually undertake more detailed entomological work to determine time of death.
