On Tuesday, Aruban authorities ruled out claims by a witness who says he knows what happened to the Mountain Brook teen.
However, a private investigator hired by Holloways father, Dave, believes that witness is telling the truth.
Holloway says his private investigator talked to Jurrien de Jong over the phone and used a voice analysis tool to test for deception.
He called me back a day or so later and said, look Dave. This guy is telling the truth, said Holloway.
The witness says he saw Natalee and Joran at a part of the Marriott hotel that was under construction in 2005. The witness told police he saw them come inside the construction area that was surrounded by a chain length fence. They went out of his sight for five minutes.
Then all of a sudden he brought Natalee down the steps in his arms. He laid her down on [a construction] platform and jumped off on the ground. He grabbed her and threw her off on the ground. Then he went a little ways and started digging under the platform area. He said he dug a hole and put her up under there. Then he covered the hole back up and walked out of the gate barefooted, Holloway recalls.
Holloway says he remembers seeing the construction area surrounded by the fence. He also remembers that no one felt led to look inside the fence because they didnt think anyone could get in that area.
Holloway says the Marriott is waiting on a warrant from Aruban police before they will allow a search.
