LIMA, Peru – Dutchman Joran van der Sloot, long the prime suspect in the 2005 disappearance of an Alabama teen in Aruba, has confessed to killing a young Peruvian woman in his Lima hotel room, a police spokesman said.

Peru’s chief police spokesman, Col. Abel Gamarra, said that Van der Sloot admitted under questioning Monday that he killed Stephany Flores, 21, on May 30.

Several Peruvian media reported that Van der Sloot killed Flores in a rage after learning she had looked up information about his past on his laptop without his permission. They did not name their sources for the information.

The newspaper La Republica said that he tearfully confessed, in the presence of a prosecutor and a state-appointed attorney, to grabbing Flores by the neck and hitting her because she had viewed photos and videos about the Aruba case on his computer while he was out buying coffee.

Gamarra would not provide details of the confession. Nor would the chief of Peru’s criminal police, Gen. Cesar Guardia. Guardia said only police director Gen. Miguel Hidalgo could authorize the information to be divulged. Hidalgo’s cell phone rang unanswered.

Asked about the Van der Sloot confession, a brother of the victim, Enrique Flores, said, “We are not going to make any comment. This is in the hands of the police, of the justice system.”

Van der Sloot’s confession came on his third full day in Peruvian police custody, on the eve of a planned trip to the hotel in which he was to participate in a reconstruction of the events leading to Flores’ slaying, Gamarra said.

Flores, a business student, was found beaten to death, her neck broken, in the 22-year-old Dutchman’s hotel room. Police said the two met playing poker at a casino.

Video from hotel security cameras shows the two entering Van der Sloot’s hotel room together at 5 a.m. Saturday and Van der Sloot leaving alone four hours later with his bags. Police say Van der Sloot also left the hotel briefly at 8:10 a.m. and returned with two cups of coffee and bread purchased across the street at a supermarket.

Gamarra said the case would now be turned over to prosecutors to present formal charges, and Van der Sloot will be assigned to a prison while he awaits trial. Murder convictions carry a maximum of 35 years in prison in Peru, and it was not immediately clear if a confession could lead to a reduced sentence.

Van der Sloot remains the prime suspect in the 2005 disappearance of Alabama teen Natalee Holloway, then 18, on the Caribbean resort island of Aruba while she was celebrating her high school graduation.

He was arrested twice in the case — and gave a number of conflicting confessions, some in TV interviews — but was freed for lack of evidence.

Holloway’s father told ABC’s “Good Morning America” on Tuesday that Van der Sloot should tell all he knows about the disappearance of his daughter.

“He confessed to this one. I would like for him to tell everyone what happened” in the earlier case, Dave Holloway said. “Hopefully, this is his last victim.”
