Then why the ransom letter written with Patsy's distintive "M" and a ransom amount for the exact odd dollar value of John's last bonus?

Perhaps these are not unrelated circumstances. The Ramsey's lived in Atlanta (the suspect's home) when JonBenet was an infant. While it is unlikely that the suspect developed any interest or relationship with JonBenet at that time, it is possible he developed a relationshop with one of her parents, and continued visiting when the Ramsey's moved to Boulder.

IIRC Jon was a baby when they left....Could he have had an eye for her older brother? Was he in the same school in GA?
