That is all fine and good, but my memory isn't that short. At the time, the Ramseys acted like guilty people - not like parents who just had their 6-year-old daughter inexplicably murdered in their basement in the middle of the night.
What about the ransom note? It was written on a pad belonging to Mrs. Ramsey. Practice notes were found. The money demanded matched Ramsey's recent bonus. Ramsey called an attorney before he called the police. Weird circumstances abound.
And then there was the Boulder police. They acted like they had all been hired that morning through CopTemp, Inc.
I can accept that the Ramseys had no part in the actual murder, but I will always believe they had more knowledge of the situation than we will ever know they had.
