I've been concerned about this, too. I heard on FOX this morning that the Aruban judge has ruled that DNA the ALE turned over cannot be used, but that the prosecution can order new samples. I thought that was old news.
As for Shango, I see many people who think he's Mansur. I really think Mansur's the one dishing out the herrings. I don't think they'll find anything in the pond or the landfill, but look how much time will have been lost...
