BIRMINGHAM, Ala. -- A cable channel is working on a television movie about a teenager from Alabama who went missing in Aruba in 2005 when she was on a graduation trip.

“The Natalee Holloway Story” is going to be based on a book by her mother, Beth Holloway. The Lifetime Movie Network has started preproduction. The movie will focus on the mother’s efforts to find out what happened to her daughter.

The 18-year-old girl from Mountain Brook, Ala., was last seen leaving a bar in Aruba with a Dutch college student and two Surinamese brothers. Extensive searches have found no trace of her.
