What's your Eerie Theory?

We haven't had a theory thread in a while, so I'm asking if you would be so kind as to tell me what you think happened, who did it, and why?

I'll go first.

I don't think this crime was sexually motivated nor do I think the person who committed it was motivated by money. I think that the person who did this was a sadistic, ghoulish, psychopath who committed murder for no other reason than to cause extreme anguish. I don't believe the murder was thought out. In my opinion, it was impulsive. It is my belief that a transient entered the Ramsey home while they were on their way to the Whites' house that night. And the information that the perpetrator had about the Ramseys was information that they obtained that night while going through the house. It's the randomness of this murder, in my opinion, that makes it so difficult to solve.

What's your theory? Please share.
