This approximate rate of heat loss continues until the environmental temperature is attained, after which it remains stable. For example, if a serial killer killed a victim in July, but the body was not discovered until October, the physiologic death took place in July, but the legal death is marked as October, since that is when the corpse was discovered and the death was legally noted.
