Natalee Holloway Confession Deemed Suspect By Authorities

A reported Natalee Holloway confession by Joran Van Der Sloot -- that he dumped the body of the American in Aruba, but did not kill her -- caused authorities to reopen the Natalee Holloway case, at least briefly.

But Radio Netherlands reports that the confession seems to be fake:

The Aruban public prosecutor's department has followed up on his statements and concluded that his latest version of events is false. The timeline is reportedly inconsistent and witnesses have contradicted Joran van der Sloot's statements.

Van Der Sloot had reportedly told German-language broadcaster RTL that he did not dump Holloway's body in the Caribbean Sea, but hid her remains in a nearby swamp.

NBC News reports that Aruba's lead prosecuter Peter Blanken calls the claims "very unbelievable."

CNN adds that RTL claims to have been first offered the footage in 2009.
