New True Crime Documentary The Serial Killer’s Apprentice Premiering August 17th on ID

Infamously known as “The Candyman Killer”, Dean Corll stalked the streets of Houston, Texas in the early to mid 1970s, luring and brutally killing at least 28 young men. Now a new documentary — The Serial Killer’s Apprentice, set to premiere on Sunday, August 17th on Investigation Discovery — explores this chilling story through a new lens with an in-depth interview with Corll’s accomplice, Elmer Wayne Henley Jr. Produced by Wolf Entertainment and Good Caper Content, the documentary is inspired by the book “The Serial Killer’s Apprentice,” co-authored by Dr Katherine Ramsland and Tracy Ullman.

Marking the first time Henley has spoken about his crimes in over 50 years, The Serial Killer’s Apprentice features Henley in conversation with renowned criminologist Dr. Katherine Ramsland. Over the course of two hours, Ramsland dives into the mind and memory of Henley – and what motivated him to act as Corll’s accomplice in what was known as the largest mass murder in US history at the time. In addition to unpacking Henley’s dynamic with Corll, the docuseries will also offer access to expansive archival footage and insight from victim’s loved ones, local authorities, and journalists who are still unpacking the extent of Corll’s crimes decades later.

Watch the trailer for The Serial Killer’s Apprentice below, and catch the documentary on Sunday, August 17 from 9-11PM ET/PT on ID and streaming on HBO Max.
