It’s the cold case that's gripped the nation – just what happened to Lyn Dawson?
It's been 36 years since anyone last saw the mother-of-two.
The Teacher's Pet podcast explores what happened on January 9, 1982, when Lyn, 33 at the time, disappeared from her home and was never been seen again.
Her husband, rugby league player Chris Dawson has long thought to have murdered Lyn. But he’s never been charged – and maintains his innocence. At the time, Chris, a school teacher, was having an affair with his student Joanne Curtis.
Now Chris' cousin Judy is speaking about the missing woman.
"We knew Lyn very well growing up and I knew how much trouble she and Chris had to go through to have those two girls [Shanelle and Sherrin]," she told Sydney radio 2GB presenter Chris Smith on Monday.
"I knew that she was absolutely devoted to them and would never have left them for a day."
Judy, who did not give her last name to the radio show, shared that she along with 500 people walked at Long Reef on September 25, to commemorate what would have been Lyn's birthday.
Judy believes justice will be served with the aid of New South Wales Police Commissioner Mick Fuller.
"I think with our new Police Commissioner… he's very dedicated to seeking justice and I think we'll see that for the family."
