NEW YORK (CBS) Police sources in Peru have disclosed to CBS News that Stephany Flores, Joran van der Sloot's alleged Peruvian murder victim, had won approximately $10,000 at casinos in the week leading up to her death and also had been given $1,000 from her father to purchase a laptop that she never got a chance to buy.
But police sources say that this money has never been found.
Flores reportedly kept her money in the glove compartment of her car. Police documents dated June 3 obtained by CBS News show the results of the search of Stephany Flores' car: no money was found in it.
Did Joran van der Sloot take that money?
The sources say that this was the true motive for the brutal murder of Flores: van der Sloot was after her money. Police say this means that van der Sloot's alleged murder of Flores was premeditated.
But in van der Sloot's confession - which he subsequently recanted in a Dutch newspaper - police say he told them that he became enraged after Flores found information on his laptop about his links to the disappearance of American teenager Natalee Holloway.
According to Peruvian newspaper La Republica, van der Sloot told police, "I did not want to do it. The girl intruded into my private life. She had no right. I went to her and I hit her. She was scared. We argued and she tried to escape. I grabbed her by the neck and I hit her."
Crimesider spoke with ex-FBI agent Paul Lindsay, who worked for many years investigating serial killers. Lindsay believes that if reports of van der Sloot's confession are accurate, van der Sloot created the story of the e-mail and the confrontation as a way to justify his actions.
Police say he smashed in the face of Flores, the student he met playing poker before leading her back to his hotel room. According to police, van der Sloot then strangled her, threw her to the floor and emptied her wallet.
Stephany Flores' death occurred exactly five years after Alabama teen Natalee Holloway disappeared in Aruba, a case which van der Sloot is the main suspect. The Dutchman faces charges of first-degree murder and robbery for the May 30 death of Stephany Flores.
