Netflix has announced a documentary on the killing of Irish national Jason Corbett, who was found dead at his home in North Carolina in 2015.

His wife Molly and her father Tom Martens were convicted of murder in 2017. They were later charged with manslaughter after a plea deal with the Davidson County's District Attorney.

They were both released from prison last June.

"When Jason Corbett, an Irish widower and father of two young children, found love again with his American au pair, Molly Martens, in 2008, their relationship seemed ripped from the pages of a storybook," reads the documentary's logline.

"The couple, along with Jason’s kids, Jack and Sarah, moved from Ireland to North Carolina to build a new life together. But on August 2, 2015, their idyllic tale took a dark turn when Jason was killed in a violent altercation at home. The perpetrators? Molly and her father, Thomas Martens — a former FBI agent. A new documentary, premiering on May 9, sheds a bright light on the many questions that have lingered since the shocking events of that night.

"Molly and Thomas claimed self-defense, the former eventually pleading no contest and the latter guilty to voluntary manslaughter in 2023 to avoid a trial, but their release from prison in June 2024 reignited questions over the incident’s true nature. Was this actually self-defense, as they argued, or a calculated killing? For some, the intricacies of Jason and Molly’s marriage add further complexity, including a long-simmering debate over the custody of Jack and Sarah, who were 10 and 8 years old, respectively, at the time of Jason’s death."

The programme is titled A Deadly American Marriage and is set to be released on 9 May.
