After confessing to the murder of Stephany Flores Ramirez, murder madman Joran van der Sloot has decided silence is the best form of defense.
van der Sloot refused to discuss his case with the Peruvian judge assigned to it Monday, RadarOnline.com has learned.
Judge Carlos Morales visited the 22-year-old Dutchman at Castro Castro prison in eastern Lima.
van der Sloot declined to give a formal statement on the facts of the case to Judge Morales, according to a court spokesperson.
The reason he gave was the ongoing motion for habeas corpus -- a legal action whereby a defendant can seek relief from unlawful detention.
van der Sloot's attorney, Maximo Altez, says his rights and due process were violated after his arrest in connection with the killing of the Peruvian student.
Altez he hopes he will be able nullify the statements van der Sloot gave to police that led to his imprisonment.
van der Sloot is charged with murder in the May 30 killing in his hotel room of a 21-year-old Lima woman he met playing poker.
He also remains the prime suspect in the 2005 disappearance in Aruba of U.S. teen Natalee Holloway.
van der Sloot has said he was "tricked" into confessing.
"In my blind panic I signed everything, but never knew what was written on them," he told De Telegraaf in a jail interview.
