The case, which garnered widespread media attention, was never solved and no one to this day has ever been charged in her disappearance.

A forensic scientist on Thursday confirmed the statement last week by Natalee’s father, Dave Holloway, that bone fragments Holloway discovered on the island where the Alabama teen vanished on a 2005 high school graduation trip “are human, and they are of Caucasian, European descent,” according to Oxygen, which is following Dave’s search for answers in its current true-crime series The Disappearance of Natalee Holloway.
