Joran van der Sloot has been charged Friday with the murder of 21-year-old Peruvian business student Stephany Flores from May 30th.
Judge Juan Buendia has ordered van der Sloot to be jailed on charges of murder and robbery, and said van der Sloot's actions showed "ferocity and great cruelty."
The judge ordered the sentence early Friday, and penal authorities are now holding van der Sloot pending trial.
Authorities said that van der Sloot took Flores to his hotel room May 30th after meeting the victim while playing poker at a local casino.
He then strangled the victim, beat her face, and stole the contents of her wallet.
La Republica newspaper reported that van der Sloot told police that after Flores took his laptop without permission and discovered that he was presumably involved in the disappearance of Natalee Holloway five years prior, he proceeded to break her neck.
Authorities revealed that 22-year-old van der Sloot provided a full confession to the beating and murder of Flores, however, van der Sloot's attorney, Maximo Altez, spoke to the press Thursday and argued that van der Sloot's confession was void because he confessed in the presence of a police-appointed defense lawyer.
Peruvian criminal chief of police, Gen. Cesar Guardia, negates Altez's remarks, citing that van der Sloot was, in fact, appointed a government defense attorney and that a Dutch translator assigned by the Dutch Embassy was also present during the interrogation and confession.
Guardia commented, "The incriminatory elements were so powerful that he had to confess."
The criminal police chief added that blood stains and other evidence were found on van der Sloot's clothing.
A media frenzy has surrounded the case, especially after van der Sloot recently revealed that he knows the whereabouts of Natalee Holloway's body.
According to reports, van der Sloot said he is willing to reveal the location of Holloway's body and divulge the events from the night the 18-year-old student from Alabama disappeared in Aruba.
Head of the Peruvian national police's homicide investigation division, Miguel Canlla, said, "In the interrogation done to the Dutch citizen, he says he knew the location of the corpse of the American citizen, but that he was going to explain everything to Aruban police."
van der Sloot has yet to be charged in the disappearance of Holloway, and if convicted on murder charges, he could face 15 to 35 years in prison.
