Break In Holloway Case?

There's a new witness in the case of American teen Natalee Holloway, who disappeared in Aruba in 2005.

The unnamed individual -- who is female -- reportedly told the Prosecutor's Office that Dutch college student Joran van der Sloot admitted to her that he was one of those who helped dump Holloway's body at sea.

Prosecutor Hans Mos is investigating, reminding reporters that van der Sloot has previously given a variety of different tales about what happened. Key among those stories is one, a secret video recording made by reporter Peter De Vries, in which the young man claims Holloway collapsed on the beach after leaving a bar.

Van der Sloot's attorney, Joseph Tacopina, told ABC news, "There was no confession, no admission of a crime by Joran on any of these tapes."
