Nearly 37 years after Lyn Dawson disappeared, police have arrested Chris Dawson over the alleged murder of his wife, taking him into custody and preparing his extradition to Sydney where he will face court. When the knock on the door came, the 70-year-old was calm. The timing may have been a surprise, but he’d known for a long time that this day may come. Calling the matter "a cold case murder", the magistrate denied Dawson's application for bail citing a high flight risk, and said the crown alleged domestic violence allegations against Chris Dawson would be raised in evidence, as well as testimony from JC. But Dawson's family believe he will be cleared, releasing a statement saying that he is innocent and that there is clear and uncontested evidence that Lyn Dawson was alive long after she left her husband and daughters.

Following an incredible groundswell of community interest ignited by this podcast, September saw a stunning development in the case with police returning to the Bayview house to conduct a new and more thorough search for the remains of Lyn Dawson. This dig was a necessity - not just to try to uncover new evidence, but also to restore public confidence and to prove to Lyn’s family that the police, this time, would do their jobs properly. Meanwhile, new witnesses come forth with compelling stories of encounters with Chris Dawson and his explosive temper. See omnystudio.com/listener for privacy information.

After 36 long years, failed police investigations, two coronial inquests, and countless appeals from Lyn's family, the case is stronger now - and once again it's in the hands of the office of the DPP. Regardless of their decision, the NSW police commissioner pledges to keep investigations going, and he plans to order a much more significant dig at the Bayview property. In this episode, former coroner Carl Milovanovich explains why he believes a jury would convict Chris over the probable murder of Lyn - and why the case still troubles him today, 15 years after his inquest in a Sydney courtroom. And Lyn's daughter Shanelle has final words in honour of her mother. See omnystudio.com/listener for privacy information.

Before the first coronial inquest, police tap phones in the lead-up to digging in a relatively small area around the swimming pool at Bayview, where they find a woman's cardigan. The crime scene officer on that dig describes what he believed were stab marks in the garment. He suspects Lyn's remains are still on the block - and may have been narrowly missed because the dig was restricted for budgetary reasons. The coronial inquests get under way and they are bad for Chris - but the system fails Lyn and her family again. See omnystudio.com/listener for privacy information.

The detective Damian Loone escalates his murder investigations, interviewing many witnesses in a quest for the truth. And the area of "soft soil" comes back into focus. See omnystudio.com/listener for privacy information.

Chris Dawson was interviewed by police in 1991, and then never again. But Sue Strath, Lyn's loyal friend, kept agitating for a further investigation, and in 1998 Detective Damian Loone was assigned to the case. Curiously, the earlier investigation notes had vanished.

After six difficult years, the volatile marriage was over. JC felt she had become ‘disposable’, as Lyn had been years before, and feared for her life. She fled back to Sydney, telling friends she was convinced Chris had murdered his first wife. In this episode, you'll hear what Chris Dawson told detectives when he was interviewed in 1991. See omnystudio.com/listener for privacy information.

Leaving the dark shadow of Lyn’s disappearance behind, Chris moved his young new wife and children north to Queensland, into a home on acreage near the newly-opened theme park, Dreamworld. Isolated behind high fences, JC lived the life of a 'Stepford wife', and was expected to meet all of her husband's demands ... including continuing to look like a school girl.

Lyn Dawson had been missing for three years when her worried friend Sue wrote to the Office of the Ombudsman - an independent government watchdog - about the lack of police action in the case. We go looking and recover a long-forgotten file after decades in storage, and the contents highlight the hopeless responses of police to a probable murder - and raise more questions, as public anger grows.

On January 15, 1984, Chris and JC wed at Bayview. With no veil, and in a non-traditional dress, the young bride looked like a flower girl. On her hand, she wore Lyn's rings. Chris's brother Paul and his wife Marilyn were witnesses. See omnystudio.com/listener for privacy information.

In the days and months following Lyn's disappearance, Chris Dawson put forth a range of suggestions as to her possible whereabouts. Perhaps she had gone north to think about their marriage. Maybe she'd joined a cult, or a religious group. But whatever he said, he clearly believed she was never going to return, as he promptly moved JC back into the family home where she became the new mother to his two children.

In January 1982, as most Australians enjoyed a carefree holiday season, Lyn Dawson was trying to pick up the tattered threads of her marriage. JC was taking tentative steps to extricate herself from her affair with Lyn's husband. And Chris Dawson was desperately seeking solutions. In this episode, a damning piece of evidence - once thought lost - is recovered, and it is something that should be vitally important to the Director of Public Prosecutions. See omnystudio.com/listener for privacy information.

Humiliated and broken by her husband's affair, Lyn finally asked JC to leave the Bayview home. The teenager walked out, and into the home of Chris's twin brother, Paul, a few hundred metres down the same street. Tensions continued to rise. And then suddenly, Lyn vanished. Years later, JC suggested Lyn's remains were buried at Bayview, in the 'soft soil' - outside what were her daughters' bedroom windows. In this episode, a surprise new witness speaks publicly for the first time about something he was told in 1987, indicating the possible whereabouts of a body. See omnystudio.com/listener for privacy information.

As Chris brazenly moved his teenage lover into the family home, Lyn saw the cracks in her marriage widen. It was crumbling all around her. Unable to believe the worst of her husband, she responded with denial, but to her family and friends Lyn's suffering was clear. And the toll was not just emotional. In this episode, a former babysitter for the Dawsons speaks for the first time about the violence she witnessed in the home. See omnystudio.com/listener for privacy information.

Cromer High School's pin-up sports teacher Chris Dawson pursued high school student JC with the sort of relentless determination he showed as a star of rugby league. Chris had model good looks, an easy charm, and students looked up to him. See omnystudio.com/listener for privacy information.

Lyn was a devoted wife and mother. She adored her husband, but he betrayed and humiliated her in the most callous way. Now she's gone - missing, a likely victim of murder. See omnystudio.com/listener for privacy information.
