In November 2021, 60 Minutes aired a special program on campers, Russell Hill and Carol Clay who had gone missing in the Victorian alpine region in March 2020.
At the time, detectives told the program they were close to catching who they believed was the killer. In fact, they were secretly recording a Victorian airline pilot — their main suspect. Greg Lynn.
A week before Lynn's arrest in late November 2021, he was at home with his wife Melanie when they watched this very 60 Minutes program about the missing campers.
Detectives said footage from roadside cameras around the area where Hill, 74, and Clay, 73, disappeared managed to account for every vehicle that left the valley that weekend, except for one. It was a mid-'90s Nissan Patrol vehicle in dark blue with a trailer.
A secret recording of Lynn in his family home captured his wife Melanie bursting out into laughter.
"It looks like your car … it really does!" she exclaimed when the program made note of a mystery mid-'90s Nissan Patrol vehicle in dark blue with a trailer - the same make and model owned by Lynn.
"It's not funny, sweetpea," Lynn replied to his wife.
This week, Lynn was convicted of the murder of Clay but found not guilty of killing Hill, after 12 jurors returned to court with a split verdict.
