Of course she was kidnapped. Abducting is kidnapping. It obviously then became a murder. Its my guess the RN was written while JBR was alive.
I'll slow down: The RN author implied that three people were involved, in the sum of his statements in the RN.
Holdontoyourhat,
The FBI Field Agents that came and took a look decided it was no kidnapping, and told the BPD this. They reckoned it was a domestic homicide.
The ransom note is fake, it is staged , it does not correspond to any crime that took place in the real world. To use it to generate any theory is a waste of time, you do not believe me, go find Lou Smit, and ask him about his intruder theory.
