Patsy, the son or one of the father's buddies makes more sense.
I'm real inclined to think the mom or the brother.
The brother might have just lost it after all the attention that got paid to Jon Benet, and the mom scribbles out the note as a cover.
Just because something makes more sense doesn't mean it is always the explanation. You need to look at the evidence. You need to look at the creeps in Boulder. Boulder has some real bad people. It is a breeding ground for radicals and terrorists. There are a lot of derelicts who use drugs hanging about. The wealthy people there are looked at with envy by many.
People who kill their children usually have problems. The Ramseys were not alcoholics or addicts. They were successful, churchgoing, active community members.
I find the beauty pagent thing sort of pretentious, but it is quite popular in the South where Patsy and John were from. It's not my thing, but so what?
It is not easy to hide the evidence you killed someone.
And the child has made DNA on her underwear supposedly.
The police are a bit vague about exactly what they've got.
I don't believe what I hear on TV. I listen to the police.

Here is a CNN article about the DNA. Now it does quote the Ramsey's lawyer, not the Boulder officials.
