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.

Joran van der Sloot has never shown any remorse for the murder of Stephany Flores, and now RadarOnline.com can exclusively reveal that the cold-hearted killer is still feeling sorry for himself, not the family of the deceased 21-year-old Peruvian student.

Currently wallowing in a maximum security prison in northern Lima serving 28 years after he pleaded guilty to the May 2010 killing, van der Sloot has been complaining about his pitiful state of mind despite confessing to the brutal crime.

Joran van der Sloot is continuing to try and garner more funds in his desperate bid to avoid the 28 year sentence that was handed down to him on January 13, RadarOnline.com has exclusively learned.

The convicted killer, who confessed to the May 2010 murder of Stephany Flores, is still asking his "guardian angel," Mary Hamer, for money despite her announcing on Sunday that she was no longer going to support him.

A source exclusively told RadarOnline.com that the 24-year-old Dutchman has been manipulating Hamer to give him more money to pay lawyer fees and pay off prison staff.

As RadarOnline.com previously reported, Hamer decided to hang up her angel wings and stop supporting Joran after sinking up to $100,000 into his legal campaign.

After announcing her resignation as the role of Joran van der Sloot’s “spiritual and civil rights advocate,” Mary Hamer has moved on to another man in need, RadarOnline.com has exclusively learned.

The Dutch killer’s guardian angel’s newest mercy mission is Amir Hekmati, the Iranian-American who was sentenced to death earlier this year on charges that he was allegedly a CIA spy.

Hamer, a radiologist from Lake City, Florida, wrote a letter on Sunday to the Iranian government begging for him to be set free, and RadarOnline.com has exclusively received the mail that she sent to the highest powers.

The woman dubbed the “guardian angel” of convicted killer Joran van der Sloot has issued a bizarre resignation letter saying she “accepts defeat” in the case.

RadarOnline has exclusively received the note from Mary Hamer, which she addressed to, among others, President Obama, Beth Holloway and Joran himself.

Hamer had paid around $100,000 in legal fees for the 24-year-old Dutchman during his murder trial. He was convicted on January 13 of beating and strangling Peruvian business student Stephany Flores after she found out he was a suspect in the disappearance of an Alabama teen from Aruba in 2005.

In an explosive interview, Joran van der Sloot’s guardian angel compared the convicted killer to the most highly respected peacemakers of modern times, and RadarOnline.com has video of her outrageous claims.

Mary Hamer, who has been paying the 24-year-old Dutchman’s legal fees during his incarceration in Peru for the 2010 murder of Stephany Flores, made the dramatic statement to Anderson Cooper in an episode that aired on Friday.

When asked if she was attracted to the devious murderer who is 31 years her junior, the Lake City, Florida woman replied adamantly: “It would be a fraud if there was a romantic relationship between Joran and me.

As Joran van der Sloot's health continues on a downward spiral in a Peruvian prison, the woman who calls herself his guardian angel opened up to Anderson Cooper about why she is going broke for the convicted killer, and RadarOnline.com has an exclusive preview of the interview.

Mary Hamer will appear on Friday's episode of Anderson, where she was shocked when the talk show host suggested she was being manipulated by the charming confessed murderer.

"Do you think he's playing you?" asked Anderson bluntly.

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.

Just a week after he pleaded guilty to the murder of Stephany Flores, convicted killer Joran van der Sloot is appealing his 28-year prison sentence, according to his Peruvian lawyer.

Attorney Jose Luis Jimenez claims that the three judges who sentenced van der Sloot on January 13 did not take into account his prior confession to the May 2010 murder of the 21-year-old Peruvian student, reported USAToday.com.

The appeal was reportedly made last week and comes in light of RadarOnline.com's exclusive report that Jimenez claims the 24-year-old Dutchman is upset with him for returning almost $75,000 that Florida woman, Joran’s “guardian angel” Mary Hamer sent him for "bail."

The depth of Joran van der Sloot's devious manipulative personality has been revealed first-hand in a letter written to the woman who has been paying his legal bills, RadarOnline.com can exclusively reveal.

In the handwritten mail, sent from Castro Castro prison in Lima, Peru to Mary Hamer of Lake City, Florida, the convicted killer begs her not to take any actions until he has found a way to call her.
