Thanks to Scared Monkeys:
Dutch investigators have been digging in the van der Sloot's back yard.
Down in the comments, there is an interview with Paulus that is quite interesting.
The most recent comment from somebody in contact with an Aruban reporter states the following:
"...at this time some trucks did arrive behind the lighthouse, with dogs and sophisticated equipment and a search is under way on that spot..."
Hoping they find her.
I will STILL never go there.
