A judge from Curacao, flown in from another island to avoid the appearance of impropriety, had his flight delayed several times Saturday and then rescheduled the hearing for Sunday morning, CNN reported.
The judge was to determine if Paul Van Der Sloot, 53, a legal official; his son Joran, 17; Satish Kalpoe, 18; his brother Deepak Kalpoe, 21; and disc jockey Steve Croes, 26, should remain in custody.
No one has been charged in the disappearance of Holloway.
Meanwhile, a team of Texas search specialists Saturday began hunting for the Alabama teen missing on the resort island of Aruba since May 30.
Tim Miller, director and founder of Texas Equusearch, said most of the 24-member search team, including eight divers and one dog, had arrived by Friday night. Three more highly trained dogs and their handlers were expected to arrive Saturday.
Miller said at least $25,000 had been raised for the search via the group's Web site.
