Strands of blond hair found stuck on duct tape in Aruba did not come from Natalee Holloway, the FBI said Thursday, the latest lead to come to nothing in the two-month old search for the missing American teenager.

The hair, which was found on July 17, was subjected to genetic testing at the FBI crime lab in Quantico, Va., and the results showed they did not come from the 18-year-old who has been missing since May 30, said spokeswoman Judy Orihuela.

“It wasn’t Natalee’s hair,” Orihuela said.

A park ranger found the duct tape on July 17 while collecting trash on Aruba’s northeast coast – the opposite side of the island from where the Alabama woman was last seen in public.

A sample of the hair also was tested at a crime lab in the Netherlands, but the results have not been released. Aruba, a Dutch protectorate, doesn’t have a lab to conduct the genetic testing.
