Its very likely neither JR or PR was even involved in their daughters murder. BR is out of the question.
Filicides just don't criminalize the murders of their children. Filicidal parents don't take their murder and make it even more criminal. They don't take something they could've called an accident (hit on the head) and add a garrote and kidnapping plot, sure to invite both the FBI and death penalty if caught. Nor do they leave 2 1/2 pages of writing for analysis. It doesn't make any sense at all. None.
- Black tape
- Strangulation cord made ahead of time.
- Ransom note with bizarre threats of violence directed at a child. Beheading a 6 year old is pretty hard core.
- Politically and socioeconomically charged references.
This is the stuff of a hard cord, hardened criminal. Got nothing to do with PR or JR being asleep. It has to do with characterizing the murder, something that the investigation falls short on, IMO.
