I surely hope that the investigators have employed the use of a good polygraph machine. They are 98% effective in determining whether a person is telling the truth or not. I don't believe these boys are adept enough at fooling a polygraph. There in lies the individual(s) who have played a role in her disappearance.
polygraph machines are not used in Aruba unless they have changed that in the past 24 hours.
Actually its confirmed they did not use them. They are going out of their way not to solve this case, being more concerned of Gov't employee son JVDS, than NH.
Sometimes I think we're assuming an investigation is taking place; vs. crisis management and damage control for those in power.
