A random pedophile who knew enough about the Ramseys to imitate their language and mannerisms in a ransom note, then use John's bonus stock amount, which no one else knew, as the ransom amount?
Clearly this was not a well planned murder, but very likely accidently and then made to look like a kidnapping.
Would a kidnapper with such elaborate plans hope to find writing paper in the home before he entered? Of course, not.
Would a kidnapper spend so much time in the home, with no idea when the family would return from the holiday party. After all, people with young children have been known to return earlier than planned.
The entire scenario spun by the Ramsey's made no sense.
They immediately hired the former Attorney General for the State of Colorado for their attorney. The message was sent!
That John Ramsey pointed the finger of suspicion at business rivals was despicable.
