Authorities have ordered a Dutch youth held in the disappearance of Natalee Holloway to provide a sample of his DNA to investigators.
A lawyer representing Joran van der Sloot said he was taken to a hospital yesterday and submitted a saliva sample for the genetic testing.
The attorney said he was told the DNA will be compared to material found by investigators.
The lawyer also said genetic material was collected from two Surinamese brothers, Deepak and Satish Kalpoe, who had been detained along with van der Sloot. The two are no longer in custody.
Investigators also plan to conduct DNA tests on blond hair attached to duct tape that was found Sunday along the island's northeast coast to see if it came from Holloway.
The Mountain Brook teen was last seen in public on May 30th.
The FBI also plans to conduct a separate genetic test on the hair. It is not immediately known when the results will be disclosed.
Meanwhile, a group of volunteer searchers from Dickinson, Texas, said today that they will return to Aruba if it turned out the hair found along the shore came from Holloway.
