Oranjestad, Aruba ? Police have a new lead in the disappearance of Alabama teen Natalee Holloway, who has been missing since last May.

Aruban police say they have a new witness in the case and will conduct another search for her body on the Dutch Caribbean island. The witness provided specific information that prompted investigators to organize a search in sand dunes along the northern tip of the island, Gerald Dompig, Aruba’s deputy chief of police said in an interview with CBS television’s “48 Hours Mystery” program.

Dompig said investigators will use cadaver dogs to search near a lighthouse and believe that someone took steps to carefully hide Holloway’s body – perhaps burying her twice. The CBS interview was scheduled for broadcast on Saturday.
