How can there be a foreign faction that has so little need of money that they ask for a mere 118,000.00? Why not 5 million or more? There is no foreign faction but the writer wants you to think so. The writer has some knowledge of political events and is not an totally uneducated person. The writer is lying in the note. There are no other "gentlemen" watching, there is no one monitoring the calls or traffic at the home. The killer is acting alone and the note stating all these facts of group participation is only a ploy to make the police, FBI, etc look for a group and not an individual.
I find it interesting that John Douglas believes the RN was written before the crime as no individual is going to be able to compose the RN after the fact. Too much excitement, adrenalin, going on to be able to write a RN. Why was the RN written on paper from the home? Two theories here- both from Douglas. The writer brought one with him but either feared being caught by it and decided to rewrite it, adding more information. Super planning- writing the RN from paper from the home to avoid being traced back to the killer.
Douglas also stated that Patsy's writing while somewhat similar, is so low on the scale of matching that a handful of other suspects matched the note better than she did.
The writer is trying to disguise handwriting.
