The last time married couple Raymond and Jennie Kehlet were seen alive was March 22, 2015.
The husband and wife from Beverley, south-east of Perth were on a prospecting trip near the Mid West town of Sandstone, 730 kilometres north-east of Perth.
The body of 47-year-old Mr Kehlet was later found at the bottom of an abandoned mine shaft, about two kilometres north of where the couple had been camping.
Despite numerous searches across the rocky, scrubby terrain no trace of Mrs Kehlet was ever uncovered.
Mystery remains unsolved
To date, no one has been charged over Mr Kehlet’s death, and many questions remain about the disappearance of 49-year-old Mrs Kehlet, who was a mother of three children.
Police found the couple’s well-stocked campsite with two vehicles and plenty of food and water.
The case shook the usually quiet town of Sandstone, which became a hive of police activity.

“It was a shock to the whole community, because that was the last thing we expected,” Beth Walton, the Shire of Sandstone president, said.
Three years on and Ms Walton said locals still want answers.
“I think the people in the town, they want closure for Jennie’s children, but also for the town; we’d just like to know what happened,” she said.
In October last year, the WA Government offered a $250,000 reward for information to solve the case.
Investigation is ‘active’ say police
Police remain tight-lipped about the case and have only said that the investigation is active, ongoing and the reward remains on offer.
They did not say if the reward had prompted any leads.

“I just hope that someone knows something and they come forward with some sort of clue that will lead to where Jennie is or what happened to her,” said Ms Walton.
“It would just be great for everybody if this mystery was solved.”
Sandstone has a population of about 50 people and although the Kehlets had little connection to Sandstone, people are quick to associate the town with the mysterious case.
“People talk about it all the time and people that come to the town … they sort of think that locals have some sort of knowledge … which of course we don’t,” said Ms Walton.
Foul play suspected
There is a strong-held belief amongst locals that foul play was involved in the case.

The search for the Kehlets began after the couple’s emaciated dog, Ella wandered into Sandstone’s local caravan park, having walked what is believed to have been 30 kilometres.
Sandstone has a long history of gold mining and prospecting, and during the recovery efforts, search crews clambered down more than 100 disused mine shafts.
Mr Kehlet’s body was eventually found in the Bell Chambers’ shaft.
In 2015, police searched a property in the southern Perth suburb of Medina and interviewed a 63-year-old man, who was later released without charge.
Ms Walton said local prospectors still keep an eye out for Jennie.
At the local pub, a small tribute has been created for the couple.
