Very very lenient prisons
Indeed, incarceration in this prison was supposed to be as good as a death sentence. Well, unless this woman is ugly enough to be considered part of van der Sloot's punishment, I'm afraid that the Peruvian prison system isn't living up to its reputation.
I guess the perp's family can afford the "luxury package". Why they continue to support this little turd is the baffling part... it's not as though he was convicted on circumstantial evidence.
