Holloway has been missing since May 30, 2005, when she disappeared during a high school graduation trip to Aruba.
The statement by the Dutch suspect aired Tuesday on German television's RTL News. But prosecutors in Aruba say they had already launched an investigation after learning of this latest confession back in August 2009, and they tell CBS News they concluded "what Van der Sloot said was not credible." They also told a Dutch TV station, "It became clear that this statement is held together by lies and fantasy."

In a statement quoted by Amsterdam's BNO News, prosecutor Peter Blanken said, "If she was left there (swamp), the chances of finding her are extremely small." He added, "After several days, nothing would have been found except bones and maybe a plastic shoe."
Van der Sloot issued a previous confession in 2007 in which he said Holloway's body was dumped at sea.
Van der Sloot's father died suddenly on a tennis court two weeks ago, at 57. Many believe Paulus van der Sloot was instrumental in covering up for his son.
