Authorities ordered a Dutch youth held in the disappearance of Natalee Holloway to provide investigators with a DNA sample, the young man's defense lawyer said Wednesday.
Joran van der Sloot was taken to a hospital Tuesday and submitted a saliva sample for the genetic testing sought by prosecutors, defense lawyer Richie Kock told The Associated Press.
Kock said he understood DNA samples also were collected from two Surinamese brothers, Deepak and Satish Kalpoe, who were detained along with van der Sloot but have since been released.
Government spokesman Ruben Trapenberg said he could not confirm the report and lawyers for the brothers were not immediately available for comment.
Authorities said the DNA would be compared to other material found by investigators but did not specify what the material was, Kock said.
Investigators said Monday they planned to conduct DNA tests on blond hair attached to duct tape that was found along the coast to see if it came from Holloway — in a possible break to the 6-week-old mystery. The FBI said it would conduct a separate genetic test on the hair. It was unknown when the results would be disclosed.
A park ranger found the duct tape while collecting trash Sunday on Aruba's northeast coast — the opposite side of the island from where the 18-year-old Alabama woman was last seen in public.
Extensive searches by Dutch marines, Aruban police, and some 2,000 volunteers have found no trace of Holloway, of Mountain Brook, Ala., last seen leaving a nightclub in the early hours of May 30 at the end of a high school graduation trip to the Dutch Caribbean island.
A group of volunteer searchers from Dickinson, Texas, said Wednesday they were prepared to return to Aruba if it turned out the hair found along the shore came from Holloway.
