Cold Case?

ORANJESTAD, Aruba -- Authorities have taken DNA samples from a jailed Dutch youth and two of his friends as investigators turn their focus to physical evidence in the case of a missing Alabama teenager, defense attorneys said Wednesday.

The samples were taken Tuesday, a day after investigators said they would conduct DNA tests on blond hair attached to duct tape that was found along Aruba's northeastern coast, in a possible break to the six-week-old disappearance of Natalee Holloway.

Joran van der Sloot, 17, was taken to a hospital and submitted a saliva sample for the genetic testing sought by prosecutors, his attorney Richie Kock said.

Two Surinamese brothers, Satish Kalpoe, 18, and Deepak Kalpoe, 21, who were detained earlier in the case but released, also submitted saliva samples the same day, said Ruud Offringa, an attorney for the older brother.

Authorities told defense attorneys the DNA would be compared to material found by investigators but did not disclose what would be used in the comparison, Offringa and Kock said.

...The saliva specimens will be sent to the Netherlands, and it could take a week or two for the findings to be disclosed, Offringa said. The test to determine if the hair came from Holloway also will take place in the Netherlands.

Aruba, a Dutch protectorate, doesn't have a lab to conduct the genetic testing.

A spokesman for the Aruban government, Ruben Trapenberg, declined to comment Wednesday on the investigation and the prosecutor could not be reached.

The FBI, which has been advising in the investigation, has said it would conduct separate genetic testing on the hair.

A park ranger found the duct tape while collecting trash Sunday on the opposite side of the island from where the 18-year-old honors student was last seen in public.

I'm glad the FBI is conducting its own genetic testing. I don't trust the Netherlands or Aruba to get anything right.

It appears there is some concrete evidence that prompted investigators to get the DNA samples from Joran van der Sloot and the Kalpoe brothers.

Maybe staying quiet won't work for van der Sloot and company after all.

Ed Hayes of Court TV points out that it's very difficult to get rid of a body in water. That's why he suspects that three drunk young guys weren't capable of disposing of Natalee Holloway's body, if they are, in fact, responsible for her disappearance.

Hayes thinks that's why authorities were questioning Paul van der Sloot.

Hopefully, taking the DNA samples signals a break in this case.
