BREAKING UPDATE: Chris Dawson has been granted bail of $1.5 million at Central Local Court following his charge and arrest for the murder and disappearance of his wife, Lynnette Dawson.
Almost 40 years have passed since the disappearance of Sydney mum of two Lyn Dawson.
Following the explosive podcast series called The Teacher's Pet, some serious questions have been raised and intriguing facts surrounding the case have come to light.
At the centre of the case is original suspect Chris Dawson, Lyn's husband. Chris drew suspicion to the case when he invited his 16-year-old lover and student, Joanne Curtis, to move into his home just two days after his wife's disappearance.
What's more, it took Chris almost six weeks to tell police his wife had gone missing, insisting at the time that she had left on her own accord to join a religious group.
While evidence has been mounting through the podcast that points to Chris Dawson being involved in Lyn's disappearance - along with two coronial inquests implicating Chris - the former high school teacher has never been charged.
So where is Chris now? We've taken a look back at the mysterious man to find out.
Chris was a former first grade rugby league player for the Newtown Jets. He then became a sports teacher at Sydney's Cromer High School in 1980, which is where he met Joanne Curtis, a 16-year-old student at the time.
The pair struck up a romantic relationship, and following Lyn's disappearance in 1982, Chris moved Joanne into his family home.The couple later married.
Chris has a twin brother named Paul. According to The Australian, Paul was known as 'Passive Paul', while Chris was 'Cranky Chris' due to his high temper and sudden angry outbursts.
The pair were very close, with Paul also becoming a high school teacher.
Chris also has two daughters, Sherryn and Shanelle, to Lyn. The pair had been reluctant to speak with media up until now.
Shanelle has not confirmed whether she believes her father is guilty or not guilty, however Sherryn has insisted on Chris's innocence.
She recently told The Gold Coast Bulletin that the investigation against her father was a "witch hunt".
Chris divorced Joanne in the late 1980s. He is now married to his third wife and lives on Queensland's Sunshine Coast.
The Daily Telegraph reported Dawson attends Gold Coast Titans training and games when he visits his brother Paul on the Coast.
It's clear the twins remain close - in August this year, A Current Affair confronted him while he was out with Paul near his home.
Reporter Chris Allen asked him: "What happened to your wife Lyn?"
Dawson simply responded: "She left".
Paul was also asked what he knows about Lyn, and he did not give a straight response.
"My concern is… it would be for… It doesn't matter… we can't make comment," he said.
