I wonder why they haven't called in the Vidocq Society? I'm reading a true-crime book called Trail of Blood by Jim Dunn. He was in basically the same situation as Natalee's parents, but it was a U.S. situation:
No body
Suspects (more than 1)
The only difference is that there WAS lots of blood.
He called in the Vidocq Society, and they used their forensic and psychological profiling skills to prosecute the murderers. They basically proved that the guy's girlfriend was a psychopath.
I wonder if Natalee's parents have contacted the Vidocq Society?
Pinging you to hispanarepublicana's post #910, for Natalee's family.
See TexKat's post #912 for direct link to this organization.
