Was the missing Aruban man ever found? If not, it's possible that he could be the one in the quarry.
I wonder if he attended one of those alleged Aruban Underground parties? The only one I am aware of, is the guy(found) who lost his head via an unknown sharp instrument.
Anything is possible as to who might be in the quarry. I am hoping that Natalee is located. I pray there may be some evidence though minute, to put the slam dunk on the perps. NSNR
