Labs in both the Netherlands and at FBI headquarters are testing hairs recovered from a piece of duct tape found in Aruba. It`s hoped that the tape will be the one clue in the disappearance of 18 year old Natalee Holloway. She vanished May 30th, when she was supposed to be returning home to Birmingham, Alabama. Searchers who found the duct tape say it had 4 hairs on it. Some blonde, some darker and about 6 inches in length.
