Australian police have arrested the husband of a Sydney woman whose disappearance in 1982 has become the subject of a popular crime podcast.
Chris Dawson, 70, is to be charged with murdering Lynette Dawson, New South Wales (NSW) authorities said. He was arrested in Queensland and would be brought to New South Wales.
Dawson has denied killing his wife, with whom he has two children. He has said that she abandoned the family for a religious group, the BBC reported.
A search of the family's former home in Sydney earlier in 2018 failed to turn up new evidence. However, police on December 5 said the arrest followed three years of renewed investigations.
"We are confident with the case," Superintendent Scott Cook told reporters. "We won't give up on trying to identify the whereabouts of Lynette Dawson, but, from our perspective, it is not crucial to finalising the matter."
Two separate inquests have recommended for murder charges to be laid against a "known person".
However, prosecutors have previously said there was insufficient evidence to lay charges. No trace of Lynette Dawson has ever been found.
An inquest in 2003 found that Chris Dawson, a former high school teacher and rugby league star, had engaged in sexual relationships with teenage students during his marriage.
One 16-year-old girl moved into the family home within days of his wife's disappearance. The pair later married, but have since separated.
A podcast "The Teacher's Pet" brought global attention to the case in 2018.
Since May, more than 27 million people have listened to the podcast, which is produced by The Australian newspaper.
It has highlighted the bungled handling of the Dawson case by police in the early years after her disappearance, prompting an apology so many years later from the state's police commissioner.
