On Monday, July 16, 2018 at 7pm ET/PT, Oxygen aired the U.S. premiere of SERIAL KILLER WITH PIERS MORGAN. In the series opener, Piers enters Florida's maximum security Blackwater River Correctional Facility to confront Mark Riebe, a convicted killer who has since confessed multiple times to the abduction and murder of thirteen women along Florida's Gulf Coast. Riebe was convicted of one murder but confessed to police to the abduction and killing of twelve women, and even though he is incarcerated for just one murder and has since withdrawn these confessions, police believe if true Riebe is one of the worst serial killers in Florida's history. In the next episode, which debuts in the U.S. on Monday, July 23 at 7pm, Piers travels to Missouri's Crossroads Correctional Facility, where he comes face to face with Lorenzo Gilyard (aka The Kansas City Strangler), and sets out to discover what drove this soft-spoken, seemingly ordinary man to kill multiple times over seventeen years. For nearly two decades Gilyard brought fear to the streets of Kansas City, Missouri. Incarcerated for six murders, he is the prime suspect in a further seven. Until now, he has never spoken about his crimes and Piers sets out to discover what drove this seemingly ordinary man to kill.
