"All this with the intention of pressuring me to accuse [myself] of homicide," the Dutch native says in the complaint, obtained by the Peruvian news program "24 Hours."
Van der Sloot, a longtime suspect in the disappearance of U.S. teen Natalee Holloway, is accused of the May 30 slaying of Stephany Flores, a 21-year-old Peruvian business student, who was found dead in his hotel room in Lima on June 2. Van der Sloot has been charged with first-degree murder and robbery in the case.
In the days following van der Sloot's arrest, officials in Peru announced he had made a full confession to Flores' murder. Van der Sloot has since retracted that confession, recently telling a journalist from Dutch newspaper De Telegraaf that police "tricked" him into admitting his guilt.
"I was scared and confused during the interrogation and wanted to leave," van der Sloot said. "In my blind panic, I signed everything but didn't know what it said."
Judge Carlos Morales Cordova of the Fourth Criminal Court in Lima was supposed to issue a ruling today on whether there is probable cause to continue holding van der Sloot behind bars. As of late this afternoon, no ruling had been issued. CNN is reporting that it could be delayed until Friday.
If the case moves forward, van der Sloot will remain in Miguel Castro Castro Prison pending trial. If convicted, he faces 15 to 35 years in prison.
Meanwhile, van der Sloot's mother has told a Dutch news station that she will not visit her son behind bars.
"I want to keep [my] distance," Anita van der Sloot said in the interview, obtained by ABC News. "I think it will bring emotions up that I am not ready for right now."
She also said her connection with her son has been damaged by the murder allegations. "There is no relationship. There's no relationship anymore," she said.
Anita van der Sloot's most recent comments come just three days after De Telegraaf quoted her as saying that her son suffered from mental problems and was "sick in his head."
Joran van der Sloot responded to those comments in his own interview with the same newspaper Tuesday, saying he could understand the position his mother was taking. "I have hurt her and too many other people," he said.
Meanwhile, Peruvian prosecutors have provided the judge with a psychological investigation report that describes van der Sloot is "emotionally immature" and "indifferent towards others' well being."
"He reflects a certain dominance over the opposite sex," an excerpt from the report reads. "He doesn't value the female role."
The report adds that van der Sloot "does not tolerate when someone tries to contradict him. It generates in him a challenging attitude. ... He presents traits of an anti-social personality."
U.S. forensic consultant Dr. Park Dietz told AOL News he is not surprised by the report's findings.
"I think if you put 100 clinicians in separate rooms and read about what he [allegedly] did, they would all say he sounds psychopathic, anti-social and hates women," he said, after reviewing the document.
If the report about van der Sloot is accurate, he added, it means van der Sloot is untreatable and should remain locked up for the rest of his life.
"There is no known treatment for anti-social personality disorder or for psychopathy," Dietz said. "It is sort of the holy grail of correctional psychiatry to find something helpful for those conditions. No one has yet, so my recommendation would be to keep him behind bars so you would never risk another woman's life."
