More theories

My theories are based on a few assumptions. I know some of them might sound really out there....and others might have been brought forward, but here they go anyway:

-It's unbelievable that no body has been yet found on such a small island. So she might be alive
-the suspects have not been cracked under intense interrogation by aruban authorities, Dutch Experts and FBI...there is a missing link here.
-BH's behaviour in relation with the chaperones has been suspicious to me.
-Do we know Twitty's or Holloway's background...does he have any connection with FBI,CIA, NSA....there where rumours he was a big shareholder in a weapon's manufacturing company. Or is there a politics connection. All this can buy determined enemies perhaps looking for revenge.

1. It wouldn't be the first time that a person would dissappear and reappear a couple of weeks or months later. Be it for partying, family feud, adventure, love, etc.

2. Insurance fraud - Perhaps NH is hiding somewhere in South America waiting for his family to receive a death certificate for the kidnapping/life insurance policy

3. Maybe NH did walk back to her room and went for a swim (which they did before) and drowned. She was intoxicated.

4. Maybe when they went to the lighthouse they took extacy pills which can be deadly when mixed with alcohol. The boys panicked and decided to hide the body (and maybe PvdS helped them here)
