Dark Voyage: Ashley's Tale

It's never happened before on "48 Hours Mystery," and maybe not ever in history. One of a serial killer's presumed victims showed up at her alleged killer's trial. Correspondent Bill Lagattuta reports from Rockhampton, Australia. Imagine the nightmare. Five women and girls were missing. Keyra Steinhardt, age 9; Natasha Ryan, 14; Sylvia Benedetti, 19, Beverly Leggo, 37, and Julie Turner, 39, vanished one after another from this picturesque small city in Queensland.
