In January 2012 a 27-year-old Adelaide man named Jayson Doelz walked into a house at Pooraka in the city's north. He didn't walk out. The court heard he was beaten for hours, tied up, thrown in the boot of a car and driven up into the Adelaide Hills, where he was stabbed to death beside a country road near Kersbrook. His body was left there.

For four years nobody was charged. Then in 2016 police made their breakthrough and arrested three men. In December 2017 a Supreme Court jury took less than two hours to find Chad Badcock, Kym Wayne Barnes and Shane Matthew Muckray guilty of murder. All three got life. And the reason prosecutors gave for the whole thing? A missing pair of sunglasses.
