SAN JUAN, Puerto Rico (AP) — A new witness has come forward in the 2005 disappearance of American teenager Natalee Holloway in Aruba, and prosecutors said Tuesday they are seeking more evidence against the only remaining suspect. A woman told Dutch police this month that Joran van der Sloot confessed to her years ago that he was involved in Holloway’s disappearance, according to Ann Angela, a spokeswoman for the Aruba Prosecutors’ Office. But the Dutch Caribbean island’s chief prosecutor said authorities still lack proof they need to convict Van der Sloot, who has been arrested twice and released for lack of evidence.—-Contact The Daily Reveille’s news staff at [email protected]
