Aruba prosecutors say Natalee Holloway's father has flown a search dog and a handler to the island to look for the missing teenager's body.
A spokeswoman for the Prosecutors' Office says the dog is searching a reservoir that witnesses have previously identified as a possible location where Holloway's remains might be found. But Ann Angela says neither police nor prosecutors have received any new leads in the case.
She said Friday in a statement that Dave Holloway took the initiative because he will not rest until he finds his daughter.
Natalee Holloway, from Mountain Brook, Ala., was last seen in May 2005 leaving a bar in the Aruban capital Oranjestad. She was 18 at the time.
