Description
Piers Morgan comes face to face with Mark Riebe, a convicted murderer who confessed to killing 13 women before retracting his claims. Serving life for the murder of pregnant mother Donna Callahan, Riebe insists his other confessions were lies. But investigators believe he knows far more than he is willing to admit.
In this tense episode of Serial Killer with Piers Morgan, Piers examines the disturbing confessions, challenges Riebe’s changing account and meets the detective who has spent decades searching for answers. He also hears from the families whose lives have been devastated by murder and disappearance, including the sister of missing mother Pamela Ray.
As the questions become more confrontational, Riebe threatens to end the interview. Can Piers uncover the truth behind his claims—and help bring answers to families still waiting to learn what happened to their loved ones?
