Chapter 1: What happened to Russell Hill and Carol Clay during their camping trip?

75.043 - 98.02 Anonymous

On Saturday March 21 2020, Andrew Marquardt, his wife and their two children woke to crisp autumn air at their campsite on the Howart High Plains in the Australian state of Victoria. Located within the Alpine National Park in the state's northeast, the area was popular with campers seeking a rugged and remote spot to be within nature.

After breakfast, the Marquardt family decided to venture down into the nearby Wanangatta Valley, hoping to find a campsite closer to the river. As they navigated the winding tracks, Andrew, an experienced bushman, kept watch for suitable clearings. At around lunchtime, he turned into what looked like a promising spot. Once inside, however, it was a different story.

A white Toyota Land Cruiser ute, apparently new, was parked in the clearing. All along its passenger side canopy were black scorch marks. On the ground beside the vehicle was what Andrew first took to be the remains of a campfire, but the blackened area sprawled far larger than any responsible camper would allow.

Drawing closer, Andrew realised he was looking at a campsite that had been entirely cremated. Chairs, awning, mattresses and a tent had all been reduced to twisted metal and dash. The only thing left standing was a toilet tent set apart from the main site. It had largely escaped the inferno save for some melted zips. The scene was cold, there was no smoke or embers, and the ash had long cooled.

The Land Cruiser stood locked and empty. Deciding to keep moving, the Marquards pressed on upstream, eventually finding a suitable spot to settle near a suspension bridge. But the memory of the burnt-out camp nagged at Andrew throughout the night. The next morning, he walked back to the incinerated site alone. Nothing had changed, yet something felt wrong.

214.119 - 241.818 Anonymous

A lead trailed from the Land Cruiser's canopy to the ground. The vehicle's passenger side mirror was missing, as though ripped off, and empty bourbon and cola cans lay scattered behind the rear wheel. Peering through a window, Andrew spotted a pink bag on the front seat. There was an esky tucked under the ute. When Andrew lifted its lid, he saw food inside that looked fresh.

Chapter 2: What was discovered at the campsite where Russell Hill and Carol Clay went missing?

244.48 - 270.878 Anonymous

Increasingly uneasy, Andrew returned to his family to talk the matter over. They wondered whether there had been an emergency and a second vehicle had taken the Land Cruiser's campers out for medical attention or supplies. With no phone reception and unable to do any more, Andrew photographed the scene. Once he was back in mobile range, he would report the discovery to the police.

Two days before Andrew Marquart discovered the burnt-out campsite, a 74-year-old named Russell Hill was preparing to go camping in the Wanangatta Valley. This would be Russell's third visit to the area in a month. Just one week earlier, he had camped for a single night in the Alpine National Park.

Chapter 3: Who was Russell Hill and what were his interests?

317.345 - 344.326 Anonymous

It was a six-hour round trip from his home in the West Gippsland town of Druin, but Russell relished his time in the great outdoors. A former forestry worker who'd later worked as a truck driver, Russell had embraced camping even more after entering retirement. He was an experienced outdoorsman and still relatively fit for his age, though he moved more deliberately than he had as a younger man.

His wife Robin didn't mind that Russell often went camping without her. He had struggled after he stopped working, confiding in a few close friends that his new phase of life was more difficult than anticipated. They had suggested he take up hobbies such as panning for gold or joining a social men's club, but these suggestions hadn't worked out.

Travelling out into the wilderness, however, seemed to be something that helped him. Early on the morning of Thursday March 19 2020, Robin helped her husband pack his bags, including a bottle of Bundaberg rum and some cans of Cougar bourbon and coke. She waved him off at 7am as he cheerfully drove away in his 2017 white Toyota Land Cruiser four-wheel drive.

The Land Cruiser had been expertly fitted out for Russell's adventures and was ideal for driving to the Wanangatta Valley Considered one of the iconic drives in the Victorian high country, the journey included striking panoramic views and challenging four-wheel drive tracks.

Russell wound the Land Cruiser through Lacola, a small town on the banks of the Macalester River, before facing the more challenging tracks, which were only accessible to all-terrain vehicles. This was Russell's territory. During his work as a forestry worker, he'd helped build many of these tracks, including the notoriously tricky Zika Spur.

445.232 - 458.705 Anonymous

Despite the remoteness of the location, Russell's journey didn't go unnoticed. Multiple people in the area saw Russell's vehicle, including a weed sprayer named Robert Williams who was working along a track.

460.037 - 486.444 Anonymous

Robert admired the Land Cruiser as it approached, noting that it was fitted out with a custom-made canopy, but was less impressed when Russell roared past him without a customary greeting or friendly wave. Robert had reason to be wary of strangers in the valley. The day before, he'd encountered what he described as a creepy fella, dressed in a singlet, shorts, and gaiters.

488.044 - 507.834 Anonymous

The man had pulled up in a four-wheel drive hauling a trailer, his clothes stained with sweat, and asked about camping spots. Robert and his fellow sprayers had a joke to darkly about the man's resemblance to infamous Australian serial killer Ivan Malat, whose crimes were covered in episode 109 of Case File.

510.689 - 527.716 Anonymous

Later, Robert spotted the same vehicle at a nearby campground known as Buck's Camp, which was a small group of sites on Dry River. It was reversed deep into the bushes with only its bull bar visible, as though its owner wished to remain unseen.

Chapter 4: What connection did Carol Clay have with Russell Hill?

782.569 - 808.642 Anonymous

Every evening at 6 o'clock, Russell joined a tight-knit group of fellow amateur radio enthusiasts on frequency 3.675 for their half-hour net, a ritual that was not only social, but a form of safety check for those who were beyond a mobile phone range. His wife Robin would often listen in on these chats as a way to keep in touch and up-to-date with her husband's travels.

The following day of Friday March 20, Russell Hill was seen by other campers. His drone was also spotted by weed sprayer Robert Williams, who was still working in the area. At around 5pm, Robert noticed the drone circling directly over his head. He wasn't a fan of the flying robots.

837.839 - 860.67 Anonymous

Although they could take good photographs for their users and provide information about the surrounding terrain, Robert found their loud buzzing sound rude and disruptive to the tranquility of the bush. Russell's purchase of the Mavic drone had also surprised some of his friends, as he wasn't typically someone who was interested in high-tech gadgets.

861.974 - 886.032 Anonymous

But it was a hobby Russell had seemed enthusiastic about, and he'd even named the new gadget, calling it Fred. The drone was a sophisticated and expensive piece of equipment, which Russell controlled through a smartphone interface. The open Wanangatta Valley provided perfect conditions for him to explore via the unmanned aerial vehicle.

As the drone circled Robert Williams several times, filming him with its camera, he waved up at it. The drone dipped in acknowledgement, then flew off. It continued to hover nearby for about 35 to 40 minutes before disappearing downstream. Not long after this, at 6pm, Russell joined his regular evening amateur radio, NET, and

915.919 - 948.461 Anonymous

Using his callsign VK3VZP, he reported he'd been having transmission issues, but sounded positive overall. His last conversation was with mate Rob Ashland, discussing possible routes toward the nearby town of Dargo. Russell signed off at 6.40pm. Rob would later say that he'd sounded as happy as a pig in shit. Russell missed the next evening's scheduled call.

949.402 - 970.762 Anonymous

His amateur radio group wasn't concerned as equipment troubles weren't unusual and he'd mentioned transmission problems the previous day. But two more days passed without any contact from Russell. During their nightly nets, the radio enthusiasts called out to their friend, asking him if he'd fallen asleep.

972.162 - 995.187 Anonymous

As the days wore on, their jokes turned to concern as they were met with only static in reply. By Friday March 27, a week had passed since Russell had last checked in with his radio buddies. Rob Ashland could no longer ignore his unease. he contacted Russell's wife, Robin.

996.648 - 1018.872 Anonymous

She confirmed that she hadn't heard from her husband since listening in on his final radio conversation, the same evening Rob had last spoken with him. When Russell failed to return home that day, Robin reported him missing, advising police that she was worried as he was alone and it was unusual for him to be out of contact for so long.

Chapter 5: What theories emerged about the disappearance of Russell Hill and Carol Clay?

1412.46 - 1439.908 Anonymous

Russell and his wife Robin had even attended Carol's first wedding. However, Russell had lied to Robin, introducing Carol to her as his cousin. Robin had believed this ruse for years. It wasn't until the early 2000s, during joint camping trips with Carol and her then-husband Linton, that Robin noticed how Russell and Carol would frequently break away from the group for private walks.

Though this made her uneasy, Robin pushed her doubts aside, wanting to believe in her husband's fidelity. The deception unravelled when a neighbour confronted Russell after witnessing Carol's visits whenever Robin was away. The neighbour gave Russell an ultimatum, confess to Robin or she would expose the affair herself.

Backed into a corner, Russell admitted everything to Robin and their daughters, swearing to end the relationship and repair his marriage. Robin had believed him, but the affair had secretly continued. Russell's solo camping trips provided perfect cover for his and Carol's continued liaisons.

He maintained the facade with a separate burner phone registered in Carol's name, ensuring no suspicious bills would reach home. The couple spoke of separating from their respective partners to be together, but only Carol ultimately went through with it. She divorced her husband to be with Russell and told her daughter Emma about the affair.

Emma felt awkward knowing about the relationship, but her mother assured her that it was very caring and loving. Carol had also confided in one of her sisters and a friend. She appeared content with the arrangement, which allowed her to maintain an intimate relationship as well as her independence in the aftermath of her divorce.

1537.088 - 1560.361 Anonymous

Most of the time Russell and Carol spent together was on their clandestine camping trips. Although camping hadn't always been an interest of Carol's, she embraced the pastime if it meant spending time with Russell. Their routine of private getaways was broken only once in January 2019, when Russell suggested meeting his friend Jim Francis.

1561.981 - 1585.964 Anonymous

Jim was travelling around Australia in his caravan when Russell called, warning that he'd be bringing a woman who wasn't his wife. Though surprised, Jim didn't pry. The trio camped together for two weeks. To Jim, Russell and Carol seemed like any other couple, freely sharing their history around the campfire.

Carol had been on another camping trip with Russell for Valentine's Day, one month before their Wanangatta expedition. As she prepared to leave with Russell again in mid-March, Carol asked some neighbours to water her plants until she returned on Sunday March 29. On the morning the couple left for their trip, Russell was seen loading Carol's bags into the boot of his Land Cruiser.

1615.61 - 1643.505 Anonymous

Carol got into the vehicle carrying a pink floral overnight bag and a clear plastic bag holding three large lever arch folders full of CWA materials. Carol had made two phone calls during the journey and had been sighted both in the Land Cruiser and at Buck's Camp. While Russell collected firewood, maintained the solar setup and secured the site, Carol managed the camp kitchen.

Chapter 6: Who is the 'Button Man' and why is he significant to this case?

In 2018, the body of Trace Lee Whittaker was found alongside strange items, but her cause of death remained undetermined. And in 2019, experienced hiker Niles Becker vanished during a planned trek, joining a growing list of those who entered the high country and never returned. The high country's unforgiving elements play a role in concealing evidence and thwarting investigations.

Extreme weather, treacherous terrain and dense vegetation can easily obscure trails and hide remains. There are also concerns that the region's isolation harbours illicit activities like illegal cannabis farms, which could potentially be linked to some disappearances.

2309.264 - 2337.006 Anonymous

While tragic accidents are certainly possible given the risks, the repeated failure to find any trace of those who have gone missing fuelled suspicions that more sinister forces may be at work. Among High Country locals there are persistent tales of what they call Hill People, former miners who have retreated into the wilderness to live untouched by society.

As detectives investigated the disappearance of Russell Hill and Carol Clay, there was one character who kept recurring in their information reports. The so-called Button Man. Described as an elderly but athletic man, the Button Man had wiry, weathered skin covered in tattoos and bone-stretched earlobes that gave him an otherworldly appearance.

He had established a camp on a remote mountainside which allowed him to observe visitors entering the park and keep count of each one by building stone pyramids to mark their passage. The reports painted the picture of an unsettling figure who appeared to take pleasure in intimidating campers and hikers.

2384.85 - 2411.147 Anonymous

The button man's moniker came from his traditional bushcraft of fashioning buttons from deer bones and antlers. Witnesses reported he had an unnerving gaze and could, quote, easily dispose of bodies. His reputation grew through reports of disconcerting encounters. The button man's interactions with campers followed a pattern.

2411.847 - 2442.325 Anonymous

He would silently materialise at their campfires, steer conversations to troubling topics and sometimes offer to show off his axe collection. His presence was felt even when unseen, as local bushmen found their hidden firewood supplies and food rations raided overnight. More and more stories spread. A sleeping marine had woken to find a tent erected noiselessly beside him during the night.

Another camper woke to find mysterious photographs on their mobile phone's camera roll. Others found inexplicable ski tracks leading from their campsite away into the alpine distance. Detectives working the hill and clay case were able to track down the almost mythic character to his camp and found him to be quite different from the stories that had sprung up about him.

2471.739 - 2499.874 Anonymous

He had been cooperative, phone records placed him far from where Russell and Carol disappeared and he never became a serious suspect. Yet, the media's fascination had already taken hold, with tabloids branding the button man as spooky and bloody scary. Locals defended him. They knew him as an eccentric but civil bushman who asked only for privacy.

On Sunday November 7, 60 Minutes aired what appeared to be a simple recap featuring Russell's daughters Debbie and Colleen and Carol's sister Jill. But Detective Inspector Andrew Stamper had an ace to play. Central to this case are these roadside cameras, he revealed, indicating footage from the valley's access roads. We've accounted for every vehicle that left that weekend, except one.

That vehicle, a dark blue mid-90s Nissan Patrol with distinctive modifications, had now become their primary focus. The grainy image showed only a side view, its occupants and number plate unclear. This revelation appeared related to investigators' earlier appeals for an unidentified Nissan Patrol, though that vehicle had been described as possibly being white.

Russell's daughter Debbie made a raw appeal to the public, stating, If someone watching knows what happened, surely your conscience is telling you that you need to speak up. Even if it's only a tiny thing, even if you only have a slight suspicion, you need to come forward so both our families can put this to rest. Casefile will be back shortly.

Chapter 8: What vehicle is being investigated in relation to the case?

The timing aligned with witness Tom Matthews' report of being woken in the middle of the night by a four-wheel drive and trailer attempting an awkward U-turn after encountering a closed road in the middle of the night. Two cameras had captured the vehicle. While one showed only a blurred side view, the other had captured the number plate clearly.

It was registered to a white Nissan Patrol, though the footage showed what appeared to be a darker coloured vehicle, possibly blue. The owner's name was Gregory Lynn and he resided in the suburb of Caroline Springs, 20 kilometres west of Melbourne. On Tuesday July 14 2020, detectives Florence and Justin paid a visit to Lynn's home.

In the driveway sat a Nissan Patrol bearing the number plate from the footage. But rather than the white of its registration or blue as captured on camera, the vehicle was beige. Detective Justin activated her recording device as Florence knocked on the front door. A middle-aged man answered, and Detective Florence assured him he wasn't in any trouble.

When asked why his vehicle wasn't white as per its registration, Lynn explained that he'd painted it blue in 2016 after returning from Central Australia. Four years later in 2020, he'd painted it beige as a COVID project with his children, using leftover Dulux metal shield in sandbank colour he'd had handy.

When asked about the trailer he had been towing, a 7 by 4 foot box trailer, Lin told them he had sold it months earlier via the classifieds website Gumtree, along with a van he'd owned and an antique sleigh bed. It was all part of a lockdown-inspired spring clean. The buyer was, quote, an Asian man, but Lin couldn't recall his name or location.

When asked about his trip to the Wanangatta Valley in March 2020, Lynn's account placed him at different campsites on different dates to Russell and Carol. He denied ever seeing the elderly couple. The detectives deliberately withheld their knowledge about the correlation between his vehicle's movements and Russell's phone data.

When detectives Florence and Justin left Lynn's home that day, they turned their attention to finding out everything they could about Gregory Lynn. Gregory Stuart Lynn was a 55-year-old commercial airline pilot. Decades earlier, he'd worked for the now-defunct Australian airline Ansett. While he came across as charismatic, some of Lynn's co-workers had found him unsettling.

One described him as a dead-set weirdo with a wicked temper. Lynn had married a woman named Lisa who was a flight attendant and colleague. They built a sprawling family home in Mount Macedon, had two sons, and, inspired by the movie Babe, bought a piglet they named Pig. To outsiders, it seemed idyllic. Behind closed doors, a darker story emerged.
