Aruba ? The mother of an Alabama honors student missing in this Caribbean island for over two months said Monday the investigation into the teen’s disappearance has been marred by ineptitude, and more than doubled the reward for help in solving the case to $250,000.

Natalee Holloway’s mother, renewing criticism of authorities on the Dutch Caribbean island, said police had given her copies of statements from witnesses and other documents from the investigation that have led her to believe investigators are on the wrong track.

“The level of ineptness has been incredible,” Beth Holloway Twitty said of Aruban authorities. “The whole thing has been wrong from the beginning.”

She declined to give details on the documents or say how she thinks authorities should be handling the case.

The family also is offering a $1 million reward for information leading to the 18-year-old’s safe return. The other reward was raised from $100,000, and Holloway Twitty wanted to publicize the rewards in neighboring Venezuela and Colombia, even though Aruban authorities and the FBI said they don’t believe the teen left the Dutch Caribbean island.

The family has said the reward is a mix of their own money and donations, but they have declined to give a breakdown.
