The father of Natalee Holloway, the American teen who went missing in Aruba 12 years ago, says he's discovered human remains that could be his daughter's. Dave Holloway and Private Investigator T.J. Ward announced on NBC's "Today" show Wednesday they discovered the remains on the island following an 18-month investigation. They are waiting on DNA tests to confirm if the remains are Natalee's. The Alabama teen vanished on a trip with friends following her high school graduation in 2005. No one has ever been charged in her disappearance.
