Paraphrasing and Recapping as I am in a hurry:
Megyn Kelly interviewing Mark Furhman on the case:
POI is actually a "press term" and NOT an LE term, Le invented it when they started talking t the press about cases. I is a term that the public is aware of, can allay fears about a crime, and shows progress in an investigation, sometimes when not enough evidence to arrest to keep "POI" on alert.
There are only 3 options or classifications following the initial conversations with police as the case is opening ( in this case they corroberated with Brad she was indeed missing and also the initial concentual searches).
They are:
1. Victim
2. Witness
3. Suspect
In his opinion there is zero evidence pointing to anyone but the husband that he has seen. He felt nancy did the groundwork and is speaking from her grave, that if she had not, that the grandparents probably would not have the children in their care right now.
If the "Bleach" purchase is true and verified, she was killed at the home.
When asked why the LE is saying they are pleased with the progress of their investigation why they won't name a suspect, he said simply they have interviewed a SMALL group of friends, and he suspects they have a strong forensic case as well as other physical evidence.
There was no mention of partially clothed, COD, and they mentioned at the end the bleach coment has not been commented on by LE other than the no confirm or deny. ( I say READ WS!!!)
