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.
