It is an interesting tape and she from what I hear, she says Daddy ... when asked what happened. I have to listen to it again more carefully to really know what else is there.
As to rigor, I posted this way back on the first thread:
"For the first hour after death, the body temperature will fall from its normal level (of about 98.6 degrees Fahrenheit) at a rate of roughly one and a half to two degrees per hour for the first twelve hours. This depends on the build of the victim, the amount of clothing or covering, and the temperature around them- if, for instance, the body is in the water the temperature will fall much quicker.
There are also other signs that can help with determining the time of death.
Usually about two hours of the person dying, rigor mortis sets in. Which is a Latin term meaning "the stiffness of death". The internal chemistry of the body changes from its normal acid state to an alkaline one. This causes the muscles which were once relaxed at the time of death to tense and stiffen. Rigor mortis begins with the eyelids and then progresses to the muscles of the face, and then to the arms, torso and finally the legs. Within twelve hours rigor mortis has been fully established and the body is stiff and as unbending as a block of unbending wood. The body can remain in this condition for any time between twelve and forty-eight hours, until the body returns to a natural acid state. This reverse process affects the muscles in the same order in which rigor mortis stiffened them from the eyelids to the legs." I confirmed it with a second link but this one is here:
