Fleet had a house full of guests - - who also had to be suspected. Both as suspects and as possible accomplices after the fact.

Priscilla was up late that night visiting with her sister - Fleet's alibi is that he was in bed alone. They lived near the Ramseys so... the theory is he could have snuck out, but I don't see it happening.

If he went over there late at night, he didn't have time to write the note....

If he planned this SO well and stole the paper days before and wrote the note before..... did he have time alone to write the note? Why no evidence of it being folded, how did he carry it? Did it look like it could have been rolled up? I doubt that since Patsy found it lying flat. And why not ask for a million? Or did he know he wasn't really there for any ransom? Was it premeditated to do what he did? If he is that sick, how could he go undetected for so long?

Could this have been planned to be SO confusing? If so, the killer was good - - REAL good!
