Oxygen True Crime’s New Documentary “The Boston Strangler: Unheard Confession” Premieres Sunday, October 26 @ 6:00PM ET/PT [VIDEO]

Oxygen, the home of  true-crime programming, uncovers shocking new details about one of the most chilling cases in American history with “The Boston Strangler: Unheard Confession.” For the first time ever, viewers will hear from the long-lost 16-hour audio tapes of alleged serial killer Albert DeSalvo’s confession, offering a raw and unfiltered account of the crimes that contradict the official story and raises new questions. Just one night before he was reportedly set to recant his confession, DeSalvo was mysteriously murdered in prison, and now, decades later, we get to hear what he really said behind closed doors.

The two-hour premiere of “The Boston Strangler: Unheard Confession” arrives on Oxygen True Crime on Sunday, October 26 @ 6:00PM ET/PT.

From 1962 to 1964, at least 11 women were found murdered in and around the Boston area at the hands of the Boston Strangler. Soon after the final murder, Albert DeSalvo confessed to 11 crimes, but was murdered in prison just one night before he was reportedly planning to recant his confession. For decades, the case was considered closed, as DeSalvo’s original confession tapes were believed to be lost and never made public – until now.

In this gripping documentary, exclusive access to the unreleased tapes raises disturbing questions. As the recordings play, DeSalvo gets key details wrong and at times seems coached to give specific answers, casting doubt on his confession and reigniting debate over the real identity of the Boston Strangler.

The documentary also includes exclusive interviews with Casey Sherman, nephew of the final victim, who dedicated his career to revealing the truth behind the Boston Strangler. Viewers will also hear from two sons of two former Boston PD detectives who worked tirelessly on the investigation, providing rare insights into how the case unfolded behind the scenes.

“The Boston Strangler: Unheard Confession” is produced by This is Just a Test, with Aengus James, Paul Lima, and Carolyn Day as executive producers.
