LIMA, Peru (AP) - Dutch murder suspect Joran van der Sloot told

police investigators that he knows the location of the body of

missing U.S. teen Natalee Holloway, the chief of Peru's criminal

police said.

"He let slip that he knew the place where this person was

buried," Gen. Cesar Guardia told The Associated Press.

Guardia said, however, that the 22-year-old Dutchman told

investigators "he would only testify (on the matter) before Aruba

authorities."

Guardia said that he didn't know how seriously to take Van der

Sloot's statement given his history of dubious statements about the

2005 disappearance in Aruba of the Alabama teen.

Van der Sloot remains the lone suspect in the case, which came

up in front of Peruvian police as the Dutchman confessed to killing

Stephany Flores, a 21-year-old woman from Lima, Guardia told the

AP.

Sheathed in a bulletproof vest, Van der Sloot was moved Thursday

across downtown Lima to a cell at the prosecutor's office as

officials prepared to file charges in the May 30 killing of Flores,

who police say he met playing poker at a casino three days earlier.

Flores was killed five years to the day after Holloway

disappeared and prosecutors have until Saturday to file charges in

the case.

Van der Sloot's newly hired attorney asked a judge Thursday to

declare his client's confession void on the grounds he made it in

the presence of a defense lawyer appointed by police.

The attorney, Maximo Altez, could not be reached directly for

comment. A person answering his cell phone identified himself as

the lawyer's secretary and said Altez was unavailable. Later calls

went unanswered.

Guardia dismissed the defense claim, calling the confession

wholly admissible in court. In addition to the government-appointed

defense attorney, he said, a translator assigned by the Dutch

Embassy was present at Monday's confession.

"The incriminatory elements were so powerful that he had to

confess," Guardia said, adding that the evidence included blood

stains found on Van der Sloot's clothing.

If tried and convicted on murder charges, Van der Sloot would

face from 15 to 35 years in prison.

Guardia said Peruvian interrogators had restricted their

questioning to the death of Flores, the daughter of a circus

promoter and former race car driver.

The May 30, 2005 disappearance of Holloway on the Dutch

Caribbean island remains unsolved.

Efforts by the FBI to try to solve it may have inadvertently

helped fund the travel that enabled the murder of Flores in Van der

Sloot's hotel room.

Believing it was closing in on Van der Sloot, the FBI videotaped

and allowed him to be paid $25,000 in a sting operation in Aruba

last month. But it held off on arresting him, and he took the money

and flew to Peru.

Guardia told the AP in an interview that the 6-foot-3

(190-centimeter-tall) Van der Sloot impressed investigators with

both his intelligence and brutality.

He said the husky Dutchman grabbed Flores and smashed her with

an elbow before strangling her and throwing her to the floor of his

room.

The general said Van der Sloot took Flores' cash, about $300

worth of Peruvian currency, two credit cards and her national ID

card.

Guardia said Van der Sloot attested to killing Flores because

she found out about the Aruba case by using his laptop without his

permission while went out for coffee.

But he said police do not necessarily believe him and think he

may have killed Flores before going out and returning to the hotel

room with two cups of coffee and rolls.

Col. Miguel Canlla, chief of homicide investigations, told the

AP that Van der Sloot took off his shirt after strangling Flores

and put it on her. He said the Dutchman wanted to put her body into

a suitcase but couldn't.

"He is cold, calculating and cynical," Canlla said.

The evidence against the Dutchman includes hotel security camera

video showing Flores and Van der Sloot entering his hotel room

together and the Dutchman leaving alone four hours later.

Security camera video from the Atlantic City early on the

morning of her death shows Flores arriving at a poker table where

Van der Sloot is sitting with other players, shaking his hand as if

they met before and then taking the seat next to him. The two later

leave together.

Van der Sloot confessed, police say, on his third full day in

police custody and a full week after he fled into northern Chile.

He was charged with extortion in the United States on June 2 -

the day of his arrest in Chile - in a case the commenced after Van

der Sloot contacted John Kelly, a New York lawyer for Holloway's

mother, Beth Twitty, in April, according to an affidavit.

The Dutchman allegedly was seeking $250,000 in exchange for the

location of the young woman's body, how she died and the identity

of those involved.

Van der Sloot's father died in February and he "wanted to come

clean, but he also wanted money," said Bo Dietl, a private

investigator who worked with Kelly on the case.

After consulting with Twitty, Kelly contacted the FBI.

It sent 10 to 12 agents to Aruba for a sting operation, he said,

in which Kelly on May 10 gave Van der Sloot $10,000 in cash and

another $15,000 was wired to a bank account.

Van der Sloot was told he would get $225,000 once the body was

found, Dietl said. According to the affidavit, Van der Sloot

insisted that a written contract be signed between him and Twitty.

Van der Sloot was secretly videotaped by the FBI in an Aruba

hotel telling Kelly he pushed Holloway down, that she hit her head

on a rock and died, the affidavit says. He said he then contacted

his father, who helped him bury the body.

Kelly and Van der Sloot went to where the Dutchman said he and

his father had put Holloway - in the foundation of a house.

No body has been found, however.

And the affidavit says Van der Sloot admitted in a May 17 e-mail

- he was in Peru by then - that he had lied about the location of

Holloway's remains.

It was not the first time Van der Sloot has admitted to having

lied about the case. Several times, he made confessions he later

retracted.

Van der Sloot was the last person seen with Holloway before the

girl vanished on the last night of a high school graduation trip.

He was arrested twice but released both times for a lack of

evidence.
