Does anyone know what has happened to this service? Their website has been down for awhile now.

Not sure, but last month there had been quite a bit of speculation in here that the prostitute that had been murdered in New Jersey was one of the girls associated with YPE.  I don't know if that was ever confirmed, but the fact the site is gone (out of business?) sure adds itself to that theory.

Quite the coincidence, huh? The news reports never actually named an service she was connected to other than the strip club in  Philly.

The young girl in question, Ashley Burg, was NOT Sabrina/Rachel of YPE. Rachel has been seen on the K since the death of Ashley Burg -- other than a passing similarity, they are totally unrelated. I suspect YPE folded because it was trying to charge escort-type prices for druggie streetwalker girls.
