This is something that occurred to me but I didn't know which thread to post it on.
Another little thing that points to there being no 'kidnapper'.....
Detective Arndt says that 10 a.m., the ransom note deadline, passed unnoticed. She says that the Ramseys did not remark whatsoever regarding the fact that the kidnapper had not called.
Much later when John was questioned about his nonchalance of the kidnapper not phoning (and he'd had time to think about it), he said it was because the ransom note stated "tomorrow" which could have implied the following day - the 27th.
Fine. So now John is expecting the kidnapper to call the following day. Right?
Yet
..
At 1:30 p.m.(less than half an hour after John had 'discovered' his daughter's body in the wine cellar) a detective overheard John Ramsey talking by phone to his pilot and arranging a trip to Atlanta that evening for himself, his wife and son. Det. Sgt. Larry Mason told him, You cant leave.
Surely the fact John wanted the family to immediately get out of the house, and out of state, shows he knew no kidnapper would be calling the following day, or ever!
