How do forensic scientists estimate cause of death for a human body?

Forensic pathologists determine the cause and manner of death by use of the postmortem examination, or autopsy. The autopsy entails careful dissection of the body to search for injury patterns, disease, or poisoning that may point to the ultimate cause of death.

How is approximate time of death determined?

The formula approximates that the body loses 1.5 degrees Fahrenheit per hour, so the rectal temperature is subtracted from the normal body temperature of 98 degrees. The difference between the two is divided by 1.5, and that final number is used to approximate the time since death.

How long does a body last in a coffin?
