I've been watching the news for sometime...and quite frankly, I don't think the Arubian men are soley to blame. Has anyone considered checking into the friend's stories?

Natalee did not return to the hotel...at what point do you as a girlfriend become concerned...why would you let a friend leave with a strange men (3 strange men)

Just speculation, but could something have happened with the friends and they hired the locals to get rid of the evidence?
