Oranjestad, Aruba (CNN) -- The piece of jawbone found on a beach in Aruba this month is human, but is not that of long-missing Alabama teenager Natalee Holloway, Aruban prosecutors said Tuesday. The piece contained a wisdom tooth, and Holloway's had been removed before her 2005 disappearance, Aruba Solicitor General Taco Stein told reporters. "Right there and then, it was obvious it wasn't Natalee," Stein said. Investigators are now trying to determine whether the bone came from any other people reported missing, he said. The bone was found by an American tourist near the Phoenix Hotel, a resort on the western side of the island, Aruban prosecutor Peter Blanken said.
