I agree with you. The note bothers me. Not for the reasons others are bothered by it but what was written. I don't think a parent, let alone 2 write this content after find their beautiful daughter unconscious. My hand would be shaking and there would be tears on that paper if I could even think what to write. I think and this is a floating theory at this point: the killer or killers had a note that they brought. For what ever reason he decided to rewrite it on her note pad. I think they were in that house for hours, and looked around at stuff and his bonus information was out, visible. It is an odd amount, but if you are younger, immature as the note suggests, maybe this is what he did, thinking he didn't want the original note for whatever reason. I think he intended to leave her there, but he ended up SA her there and then had to hit her to end it. I think we can agree that there was nothing professional about this murder. So that is what I am think for now.
