The mysterious case of two missing campers could be on the verge of a breakthrough as detectives believe 'someone tried to cover their tracks' - with their devastated families pleading for answers.
Russell Hill, 74, and Carol Clay, 73, who were having a secret affair, haven't been seen since March 2020 when they were camping at the Wonnangatta Valley in the Victorian Alps.
Police have been dogged in their ongoing investigation, but so far have failed to locate the pair - or any distinct signs of their possible remains.
However, detectives revealed new information into their disappearance in a preview for Sunday's 60 Minutes, confirming 'someone tried to cover their tracks' and that they are honing in on new targets.

Mr Hill left his home in Drouin, in Victoria's Gippsland region, on March 19 last year and collected Ms Clay from her home in the south eastern Melbourne suburb of Pakenham in his Toyota Land Cruiser.
They travelled through Licola, spending one night at Howitt High Plains before heading into Wonnangatta Valley where they vanished without a trace.
Mr Hill was last heard from on March 20 over the radio telling friends he was in Wonnangatta Valley, while Ms Clay had told friends she was heading away and was expecting to return by March 29.
A friend of Ms Clay revealed she knew she was heading on the trip with her secret lover in the 60 Minutes preview.

'I feel like there's always that little glimmer of hope he might come back,' Mr Hill's daughter said.
The area is notorious for blood-thirsty hunters illegally killing deer, who often use thermal imaging with their high-powered rifles to shoot at prey from as far away as 800 metres
