David Holloway of Meridian has traveled to Aruba to aid in the search for his missing daughter.
Natalee Holloway, a graduate of Mountain Brook High School near Birmingham, disappeared during a senior trip.
David Holloway and Beth Holloway Twitty, Natalee's mother, and several family members were expected to arrive in Aruba Wednesday to aid the search.
Birmingham FBI spokesman, Special Agent Jeff Fuqua, says his agency is coordinating with FBI officials in the Caribbean to search for Holloway. She took the trip with other graduating seniors and adults after her May 24 graduation.
Other students say she never showed up for the group's return flight Monday. Police in Aruba also say they're searching for Holloway.
Other members of her class say about 125 graduating seniors and adults took the five-day trip. It's an annual tradition not sponsored by the school.
