Joran van der Sloot is desperate to get back home to the comforts of Castro Castro prison and he is not afraid to pay Peruvian officials in order to get there, RadarOnline.com is exclusively reporting.

The convicted killer is currently serving 28 years in the maximum security Piedras Gordas facility for the May 2010 murder of student Stephany Flores, but he is determined not to be there for long, according to an insider.

It's less than a month since Joran van der Sloot was sentenced to 28 years for the murder of Stephany Flores, but the cold-hearted killer is hoping to be a free man in less than five years, RadarOnline.com has exclusively learned.

"He is appealing his sentence and hopes he gets parole in less than five years," an insider exclusively revealed to RadarOnline.com.

If van der Sloot's prediction comes true, it will mean he is a free man by 2017 and will serve a fraction of the sentence that was handed to him on January 13 after he confessed to the May 2010 killing of the 21-year-old Peruvian student.

Joran van der Sloot is no stranger to life in jail but his new home is a far cry from the luxuries he had grown used to during his 18 months at Lima's Castro Castro prison.

After he was sentenced to 28 years on January 13 for the May 2010 murder of Stephany Flores, van der Sloot was transferred to the high security facility of Piedras Gordas in northern Lima in response to criticism that his living conditions were too comfortable, and RadarOnline.com can exclusively reveal that since the move his health has been in a downward spiral.

In light of Wednesday's confession to the murder of Stephany Flores, Joran van der Sloot now faces a prison sentence that could be far less than if he had gone to trial, but his self-professed "guardian angel" wants him to be released all together, claiming that in 2022 Joran will be presenting “his thesis of peace to the world.”

Mary Hamer, of Lake City, Florida, who has been paying the Dutchman's legal fees during his incarceration in Lima's Castro Castro prison, wrote a letter of appeal on Thursday to Peruvian President Ollanta Humala asking for Joran to be placed in her care.

"My humble request for clemency and mercy for honest and sincere statement of confession of Joran van der Sloot. Please release Mr. van der Sloot to me for 10 years Gandhi Nonviolence Program," wrote Hamer, in Spanish.

Murder suspect Joran van der Sloot is willing to confess to the "simple homicide" of Stephany Flores but will fight the more serious charges that could keep him in prison for life, RadarOnline.com has learned.

The Dutchman's attorney Luis Jiminez Navarro told a Lima, Peru court in writing on Monday that van der Sloot was willing to admit to the lesser charge but not to one akin to aggravated murder, which carries a maximum sentence of life in prison, reported CNN.com.

A simple homicide charge carries a maximum sentence of 20 years in prison.

Six years after Natalee Holloway went missing in Aruba, the prime suspect in her disappearance will be in a Lima, Peru court Monday -- this time for the murder of Stephany Flores.

Joran van der Sloot was officially charged on September 1 with killing the 21-year-old Peruvian student, and Monday he'll be before a judge for the preliminary hearing in the case.

The Dutchman was arrested for the grisly slaying in June, 2010 and has been held in Lima’s run-down Castro Castro prison ever since.
