Killer Chris Dawson's third marriage to his wife Susan (above together in April this year) in three decades has fallen apart as the woman killer begins his lengthy prison sentence, which is expected to see him die in prison

Murderer Chris Dawson has been ‘split’ from his faithful third wife as he begins his lengthy prison sentence, which will likely see him die in prison.

Former teacher Susan Constance Dawson, who has been married to Chris for nearly three decades, was not present for his marathon murder trial, sensational verdict and sentencing hearings.

But Ms Dawson had stayed with the ex-footballer through years of media scrutiny sparked by two investigations in 2000 and 2003, and the global spotlight brought on by The Teacher’s Pet podcast.

Following Judge Ian Harrison’s sentencing of Dawson to a maximum of 24 years in prison last week, journalist Hedley Thomas revealed on the podcast that Susan Dawson and Chris Dawson were “estranged, that the marriage failed.”

Daily Mail Australia can also reveal that the Gold Coast home that Susan and Chris Dawson shared leading up to his December 2020 murder arrest was sold on November 15 for approximately $1.1 million.

The classic four-bedroom beach house in Biggera Waters, which the Dawsons bought for $399,000 in 2011, went on the market just two weeks after Judge Harrison found Chris guilty of murder and sent him off to jail.

It was in Biggera Waters where Dawson was arrested and charged with the murder of first wife Lynette at their home in Bayview, Sydney on January 8 or 9, 1982.

Susan and Chris Dawson appear to still own another home together, on Mount Coolum on the Sunshine Coast.

In April of this year, the month before Dawson’s murder trial began, he was photographed while Susan was shopping for household goods at Target, in Runaway Bay on the Gold Coast.

Earlier in the same day, he was photographed reporting to Maroochydore Police Station as per his bail conditions before driving the two hours south to have lunch with Susan and then go shopping.

Dawson had fought all the way to the Supreme Court for a permanent stay in his murder trial, but in February 2020 he was determined to stand trial.

Chris Dawson’s marriage to Susan has been his longest.

His first marriage to Lynette ended after 12 years when he killed her in 1982.

Chris and Lynette had two daughters, aged four and two at the time of her murder.

His second marriage in 1984 to babysitter JC, which produced a daughter in 1985, ended when she left him in 1990. The couple divorced in 1993.

Dawson is said to have met Susan, who had divorced her husband and had two young children, in 1990, shortly after JC fled with her and Chris Dawson’s five-year-old child.

Susan’s children took Dawson’s surname.

Susan was working as a physics teacher at St Brendan’s Catholic Boys School on Queensland’s Capricorn Coast when she met Dawson, who was working as a PE teacher at St Ursula’s Girls College, also in Yeppoon.

Judge Harrison said in his own sentencing comments last week that Dawson’s relationship with Susan had “suffered” under the weight of his circumstances, but that the marriage was still intact.

“Mr. Dawson has enjoyed 36 years in the community, unencumbered by the taint of a conviction for killing his wife or any punishment for it,” said Judge Harrison, as he considered the killer’s plea for a reduced sentence.

“He married JC and they had a child. He remarried not long after their divorce and has remained so, even though that relationship has suffered from the events that took place,” said Judge Harrison.

Chris Dawson’s reported marital breakup with Susan comes as he has also been separated from his identical twin brother Paul for the longest time since their birth in 1948.

The Dawson twins, of whom Paul was the first born, had their own childhood language, played soccer together, worked together as gym teachers and other odd jobs, lived on the same street, and once had Twin1 and Twin2 license plates.

But ever since Chris was found guilty, handcuffed and led out of Courtroom 13A on the afternoon of August 30, causing Paul to run out of the room and say “bulls***,” the twins have split up.

Paul, who is believed to live in Paradise Point on the Gold Coast with his wife Marilyn, is said to be one of six contacts Chris Dawson is allowed to call from prison on a landline he shares with other inmates.

In phone interceptions played by Dawson’s counsel during the murder trial, the twins seemed to call each other just after 9 p.m. every day.

In prison, however, inmates usually get their dinner and are locked in their cells around 3:30 PM.
