An upcoming Netflix documentary on Jason Corbett’s murder is an opportunity for the Limerick man’s family to set the record straight, a source close to the production has said. The 39-year-old was brutally beaten to death by his wife, Molly Martens and her father, Tom, in the couple’s North Carolina home in August 2015. Today's top videos STORY CONTINUES BELOW Mr Corbett’s children, Jack and Sarah, 10 and eight at the time, will be ‘absolutely central’ to the one-off Netflix programme announced this week, which will also interview his killers. Jason Corbett with his children, Sarah and Jack. Extra.ie has learned the documentary, titled A Deadly American Marriage and set for release on May 9 – was initiated by Mr Corbett’s family, who had felt ‘burnt’ by a programme broadcast in the US in 2017. Mr Corbett’s family had not been asked to contribute to that 20/20 documentary, which went out on the ABC network days after the Martenses were convicted. It introduced allegations that Mr Corbett’s first wife, Margaret Fitzpatrick Corbett’s died after an asthma attack was mysterious, as well as new claims about domestic abuse that the court hadn’t heard. A source close to the new Netflix production told Extra that Mr Corbett’s children, who are now aged 20 and 18, will be ‘absolutely central to the documentary’. ‘The story kind of begins and ends with them,’ said the source. Molly Martens.

The children had initially told investigators that their father had anger issues and had been abusive, but later renounced their claims, saying they had been coached by Ms Martens ahead of giving their statements. ‘It’s an extraordinary human story from the point of view of those two kids,’ the source said. Molly and Tom Martens were tried for murder in the years following Jason Corbett’s killing, which they claimed had taken place in self-defence.

They were released last June, after serving just four years and three months in prison. The Martens family had also used Ms Fitzpatrick Corbett’s 2006 death in a last-ditch attempt to paint Mr Corbett as a monster during sentencing hearings 18 months ago. Following a claim made by their defence team that Jack and Sarah’s mother may actually have died from strangulation, a forensic pathologist called by the prosecution as an expert witness questioned the original Irish autopsy report. The pathologist said it was possible that Ms Fitzpatrick Corbett may have died from strangulation and not an asthma attack. This prompted a furious rebuke from the Fitzpatrick family, who spoke of ‘wildly inaccurate and untrue lies’ in a statement. Jason Corbett. The family clarified that the deceased’s sister had been present on the night of the asthma attack, and that Ms Fitzpatrick Corbett’s distraught husband had done everything in his power to save the mother of his two children. Tom and Molly Martens have also been interviewed for the new Netflix documentary. The source noted that the killers had deliberately ‘used the media from day one to put out allegations that never actually formed part of the court case’. ‘They managed to influence public opinion, largely through Facebook posts. You had the situation where, within a week of them being convicted in 2017, you had millions of people watching the ABC 20/20 programme, where Jason was depicted as a domestic abuser and as someone who regularly physically assaulted Molly Martens, and none of that had been entered into court.’ The Netflix show has been in the making for four years, with production held up by judicial delays caused by the pandemic and suspended for over a year while discussions were ongoing over a plea deal for the Martenses. Sarah Corbett Lynch published a memoir earlier this year entitled ‘A Time For Truth’. In it, she describes her stepmother as abusive, manipulative and volatile. Journalist Brian Carroll, who is a co-producer on the upcoming Netflix documentary, is due to publish a new book on the case later this year.
