An Aruban official says a private investigator will continue scouring a pond for signs of missing U.S. teen Natalee Holloway, even though he has not found any clues into her 2005 disappearance.

Ruben Croes, president of the Aruba Search and Rescue Foundation, said investigator Fred Golba told him Tuesday that he "hasn't found anything of interest" in the drained pond and plans to search for another week.

Aruban volunteers are aiding the investigator as he searches the pond that witnesses previously identified as a possible location for her remains.

Golba was hired by Holloway's father to search the pond even though it has been scoured before.

Holloway, from Mountain Brook, Alabama, vanished in May 2005.
