The Truro murders was the name given to the findings of the remains of seven young women in bushland near the town of Truro, South Australia in 1976 - 1977.

Miller stood trial for the murders, and was found guilty of six of the seven murders. Interestingly, he was convicted of murder despite having never touched a victim. The testimony at his trial revealed a terrifying story. Miller and Worrell would regularly cruise the local streets, looking for women that Worrell could have sex with. Worrell was charismatic and good-looking, and this was a time of sexual revolution in Australia, so Worrell regularly "picked up" local girls. Miller would drive Worrell and the woman to a secluded place, where Worrell would have sex with the woman while Miller waited outside the car. Then Miller would drive them back into town.
