Roughly 845 kilometres north of Adelaide on the Stuart Highway sits Coober Pedy. A tiny, opal-rich desert town pockmarked by mining shafts and dugout homes that have been built into the sun-scorched earth.
It’s a place just 1700 people call home; countless more come and go, with or without their longed-for fortune. But it’s also a place that’s home to more than its share of mystery.
Between 1990 and 2003, four murders took place in Coober Pedy, all of which remain unsolved. Two decades on, South Australia Police are reviving their investigations into the crimes as part of Operation Persist – an initiative launched in 2015 to review the state’s cold cases.
And now, police are acknowledging possible connections between two.
Karen Williams, 16, and Anna Rosa Liva, 30; two women who disappeared from the town just 14 months apart. Karen, a member of the local Aboriginal community, vanished on August 4, 1990 after a night out with family and friends. Anna Rosa, an Italian tourist, was last seen on November 28, 1991.
Neither woman’s body has ever been found.
Karen Williams’ disappearance.
After a celebration at Sergio’s Restaurant on Coober Pedy’s main street, TAFE student Karen and three friends accepted a lift from a man in the early hours of August 4. While her friends got out of the vehicle near Medway Drive, Karen didn’t.
A short time later, around 5am, the teenager was seen in a vehicle at the local Caltex Service Station.
That was the last known time she was ever seen alive.
Following an extensive inquiry, police charged a man named Nikola Novakovic with Karen’s murder, but in August 2016 he was acquitted by a Supreme Court judge.
A reward of $1,000,000 is available to anyone who provides information leading to the apprehension/conviction of the person or people responsible for her suspected murder and/or leading to the location and recovery of her remains.
