Tipper, if the BTK investigators or the Green River investigators, had one tenth of the evidence the Boulder D.A. has against the Ramseys, their suspects would have been arrested within a few days.
The evidence is there. They just won't do anything.
Keenan, if she has a decent bone in her body, by now should be mortified that she even thought that Santa Bill did the crime.
In once sense you are right. There is no evidence left to investigate as far as the "Intruder" goes. Because there was no intruder. Can't investigate something that does not exist.
