Birmingham, Ala (WIAT)  Apparently Joran van der Sloot's new digs aren't as appealing as his stay at the Castro Castro prison.  Several websites are quoting "insiders" who say the convicted murderer's health is deteriorating at the high security Piedras Gordas facility North of Lima.

The Dutchman was moved there recently after his conviction and 28 year sentence for killing Stephany Flores. He confessed he killed the 21 year old student after she found material about Natalee Holloway on his laptop in his hotel room.

RadarOnline has this comment from an "insider":   'His health has suffered and he is not doing well there. 'Joran blames the food and the water, he says that he is depressed and feeling weak all the time.'

This is in apparent contrast to what critics, including the dead girl's family, called his "royal treatment" at the Castro Castro prison where he spent a year and a half after Flores corpse was found in his Lima hotel room. That grim discovery was made five years to the day that Mountain Brook teen Natalee Holloway walked out of a bar on Aruba, with van der Sloot, and was never seen again.

While at the Castro Castro, van der Sloot made a steady stream of headlines world wide for everything from drug sales and purchases to mugging with other accused murderers. He was even accused of fathering a child during conjugal visits...a claim that was never proven.

His new prison is a maximum security lockup but there may be an even harsher prison in his future. Van der Sloot has expressed concern he could be transferred to the notorious Challapalca Prison, in Tacna, southern Peru.

And whenever the end of his stay in Peruvian prisons comes, the U.S. Attorney here in Birmingham is waiting to try him on extortion and wire fraud charges. The feds say van der Sloot took money from the Holloway family after promising to tell them where to find Natalee's body. He never came up with the information but apparently used the money to travel to Peru where he met Stephany Flores at a poker tournament.
