Convicted murderer JORAN van der SLOOT is no longer enjoying “la vida loca’ in his new maximum security prison.

The luxuries he enjoyed for a a year and a half while awaiting trial for murder in Lima’s Castro Castro are over in his new home at the high security facility of Piedras Gordas. reported the Dutch thug’s health is a downward spiral since his sentencing for the murder of Stephany Flores.

"His health has suffered and he is not doing well there," an insider said

"Joran blames the food and the water, he says that he is depressed and feeling weak all the time."

During his time at Castro Castro, the prime suspect in the disappearance of Alabhama teen Natalee Holloway, Joran had access to books, money, calling cards, internet access – and even conjugal visits.

As The ENQUIRER reported, van der Sloot was alleged to have gotten his girlfriend pregnant while he was incarcerated. Although his former lawyer denied the baby rumors, he admitted sex was permitted behind bars.

“Conjugal visits are allowed at the prison and women regularly visit to see inmates – Joran had girlfriends come and see him and he did have sex but he did not get any of them pregnant," said Maximo Altez Navarro.

But now, Joran remains in solitary confinement Piedras Gordas, a 161,458 square foot maximum security detention center located in a barren desert miles from Lima.

Not only are there no conjugal visits there is no yard time for the hulking 24 year old —  and things could get worse!

There is a very strong possibility he’ll be sent to the notorious Challapalca Prison, in the cold and inhospitable area of Tacna.

In 2002, a special investigation into the violation of human rights resulted in a report that recommended to the Peruvian State that “the prisons at Challapalca and Yanamayo be deemed unfit to serve that purpose, and that the personnel detained at those prisons be transferred to other prisons.”

Joran's lawyer, Jose Luis Jimenez, is currently fighting to make sure that his client doesn't end his days in the frozen penal colony, and has filed an appeal against his sentence.

Good luck with THAT!
