‘Teacher’s Pet’ subject convicted of wife’s 1982 murder after true crime podcast sheds new light on cold case

An Australian man was convicted of the cold case murder of his wife Tuesday after a true crime podcast brought widespread attention to the case in 2018.

A judge found that Christopher Dawson, a 74-year-old former high school teacher, killed his then-wife Lynette Dawson in 1982. 

At the time of his wife’s murder, Dawson was involved in an extramarital affair with the 16-year-old babysitter of their two daughters, ages 2 and 4 at the time, according to a 2003 court proceeding called an inquest. She was a former student – and days after Lynette Dawson’s disappearance, the teen moved in with Christopher Dawson. They married after she turned 18 and split four years later.

Hedley Thomas, an investigative reporter for The Australian newspaper, chronicled the case on his podcast, “The Teacher’s Pet.”

Australian court records show Dawson, a former professional rugby player who became a high school teacher, had asked for a trial by judge, giving up his right to a jury, citing the podcast’s large audience.

Thomas did not immediately respond to a request for comment Tuesday afternoon – the early morning local time.

The conviction was “40 years overdue,” he wrote in an essay published after the verdict.

“It was a hopelessly one-sided spectator affair,” he wrote of the proceedings. “Almost everyone there wanted Dawson in handcuffs before lunch.”

The podcast attracted a global audience of roughly 60 million and cast renewed scrutiny on the case. Australian police arrested Dawson at his Queensland home in December 2018.

Dawson reported his wife missing on Feb. 18, 1982, according to New South Wales police. But her last known contact came more than a month earlier, when she spoke with her mother on Jan. 8. They made plans to for lunch the next day. She didn’t show up.

Her body has not been found.

“The whole of the circumstantial evidence satisfies me that Lynette Dawson is dead, that she died on or about Jan. 8, 1982 and that she did not voluntarily abandon her home,” Judge Ian Harrison said in court, according to the Associated Press.

He said that Dawson had lied about receiving phone calls from his wife following her disappearance and called the argument that she may have run out of her family “ludicrous.”

Dawson faces up to life imprisonment.
