Netherlands ? The mother of missing American teenager Natalee Holloway said that she’s now convinced her daughter is dead after watching hidden camera footage of a Dutch student allegedly acknowledging involvement, according to an interview published Saturday.

“I can let her go now and begin mourning,” Beth Twitty said in an interview late Friday with the best-selling Dutch daily De Telegraaf. “The 1 percent of hope I had that she was still alive is gone.”

Joran van der Sloot on Friday denied that he had anything to do with Holloway’s disappearance in Aruba, saying he lied when he told someone privately he was involved.

Van der Sloot was interviewed by the respected Dutch television show “Pauw & Witteman” following reports that crime reporter Peter R. De Vries had captured him making statements about the case.

It was not known whether Twitty had heard of Van der Sloot’s denial before she spoke with the Dutch newspaper. Twitty, who is in the Netherlands at De Vries’ invitation, was not available to speak Saturday, said Peter Schouten, a spokesman for the crime reporter’s show.
