Good Lord, Ames.
I think here we have a strong clue in favor of the idea that the R's original plan was to get JBR's body out of the house, and dump it somewhere!
What are baby teeth used for?
DNA comparisons of remains.
I think that taking the baby teeth was originally planned to do one of two things: one, make the eventual identification of JBR's body very difficult, or two, allow the R's to identify the first remains of a female child about the right age as JBR's body.
But, of course, the plans changed, JBR's body was 'discovered' in the house on the 26th, and the R's left without a backward glance.
But somehow "baby teeth" ended up on a list used by Pam Paugh on her infamous house raid!
Is it possible the "list" was made the night of the crime, or that when it was made, someone's ideas about what they needed to get out of the house were still confused by the changing scenarios of the night of the murder?
