Josie goes full outback, taking Mel through the case of Jennie and Ray Kehlet, who in 2015 went on an amateur gold prospecting trip to a remote part of WA - and never returned.

If zesty banter isn't your thing, skip to 6:14 for the mystery to start.

If you have any information about the case, contact Crimestoppers on 1800 333 000.
