Case 70

The Kimberley Killer

*** Content Warning: gun violence ***

In June 1987,  the bodies of Phillip Walkemeyer, Julie Warren and Terry Bolt were found shot dead at a campsite at the Pentecost River Crossing in Western Australia’s Kimberley Region. Their burnt-out vehicle was found nearby. Similarities were drawn to the double homicide of father and son, Marcus and Lance Bullen, that occurred days earlier at a remote river hundreds of kilometres away in the Northern Territory. 

This would be no easy investigation. The murders occurred in the rugged, isolated wilderness, where off-road travel was strongly advised against without the help of an experienced guide. These were the kind of areas people visited in search of solitude and isolation. So just how do you catch a serial killer in one of the most remote areas of Australia?
