On April 25, 1978, William "Bill" Thomas and Valda Thomas found what they thought was the bone from the leg of a cow whilst mushrooming in bushland near the South Australian town of Truro.Upon closer inspection, they noted that the bone had a shoe attached; inside the shoe was human skin and painted toenails. Clothes, blood stains, and more bones were found nearby. The remains were later identified as those of Veronica Knight, an 18-year-old girl who had vanished from an Adelaide street around Christmas of 1976.
Almost one year later, on April 15, 1979, four bushwalkers discovered the skeletal remains of 16-year-old Sylvia Pittman, about 1 km from where Veronica's remains had been located. Pittman had disappeared around the same time as Knight.
Serial killing was a new phenomenon in Australia at the time, and police faced a difficult task of piecing together evidence. There was the strong suggestion of a link between the two dead women found in the Truro bushland and five other young women reported missing in Adelaide at the time.
Eleven days later a huge search party discovered two more skeletons in a paddock on the opposite side of the road.They were the remains of Connie Iordanides and Vicki Howell, two of the five missing girls.
Christopher Worrell, described as young, charismatic and psychosociopathic, and James Miller, a 40-year-old labourer, described as a drifter and homosexual partner of Worrell, are believed to have committed the murders.
Miller first met Worrell when both were in prison together, Miller for breaking and entering, Worrell for rape and breaching a two year suspended sentence for armed robbery. After release they formed a dominant/submissive relationship and both lived and worked together. Miller was infatuated with him and Worrell would allow Miller to perform sexual acts on him while he read pornographic, and predominantly BDSM, magazines. As Worrell preferred women this later ceased and they became more like brothers.
Worrell and a female friend were killed in a car accident on February 19, 1977, thus ending the murders. Miller survived the car accident.
Miller suffered depression and became homeless after Worrell's death. Miller's state of mind and a chance comment were to eventually give police a breakthrough when at Worrell's funeral, his former girlfriend, Amelia, told Miller that Worrell had had a suspected blood clot on the brain. This announcement prompted Miller to tell her about Worrell's fascination with thrill killing, suggesting that the clot might possibly have been responsible for the moods that led Worrell to kill.
In May 1979, she collected a AUD$30,000 reward after providing the information to police leading to Miller's arrest and capture. Amelia said that she had not come forward earlier because she had no proof the admission was true and that there was not much point in going to the police as Worrell was dead. It was only after reading of the murders in the newspaper that she came forward. It is highly likely that the murders would have gone unsolved if Amelia had not come forward.
Miller was brought in for questioning on May 23, 1979. Initially he denied knowing anything, but eventually stated that Amelia had "done what I should have" and told detectives that there were three more bodies. Miller was driven under guard to Truro, Port Gawler and the Wingfield dump where he pointed out their locations.
- Veronica Knight (December 23, 1976; aged 18)Veronica had become separated from her friend while shopping and accepted a ride home. Miller claims they talked her into going for a drive in the Adelaide foothills. Worrell parked while Miller went for a walk. Returning to the car he found Veronica dead; Miller alleged that he angrily confronted Worrell, who pulled a knife and threatened him. Worrell was in a black mood and wouldn't talk; Miller helped him dump the body at Truro. They both returned to work the next morning.
- Tania Kenny (January 2, 1977; aged 15)Miller and Worrell picked up Tania after she had just arrived in the city after hitchhiking from Victor Harbor. They drove to Miller's sister's home and Miller sat in the car while Worrell and Tania went inside. Worrell later returned and asked for help. Allegedly an argument occurred and Worrell threatened to kill Miller if he did not help. That night they buried Tania at Wingfield.
- Juliet Mykyta (January 21, 1977; aged 16)Julie was waiting at a bus stop after finishing a part time job in the city when Worrell offered her a lift home. Instead he drove her to Port Wakefield. This time Miller sat in the car while Worrell tied her up. This behaviour was not unusual—"it was Worrell's kink"—so Miller thought nothing of it. Miller alleges he then went to take a walk but turned around after hearing a disturbance. Julie was out of the car and falling to the ground. Worrell turned her over and began strangling her. Miller claims that he tried to pull Worrell off, but was not strong enough, and that again Worrell threatened to kill him. Later Julie joined the others at Truro.
- Sylvia Pittman (February 6, 1977; aged 16)Picked up as she waited for a train at the Adelaide Railway Station. They drove to the Wingfield area where Miller went for a walk and later helped dispose of the body at Truro.
- Vickie Howell (February 7, 1977; aged 26)Worrell rang Miller to pick him up from the Adelaide Post Office. When he arrived, Vickie was already with Worrell. She had recently separated from her husband and was happy to go with them to Nuriootpa. Stopping the car, Miller went for a walk; after soon returning, but finding nothing untoward, he then took a longer walk. When he returned, Vickie was dead and Worrell was in a rage. Miller claims that he cursed and abused Worrell, expecting to be killed himself, but Worrell said nothing. Vickie's body was then taken to Truro.
- Connie Iordanides (also known as Connie Jordan; February 9, 1977; aged 16)Picked up in the city centre and offered a lift home, Connie became frightened when then they drove in the wrong direction. Miller stopped at Wingfield and Worrell forced the screaming girl into the back seat while Miller did nothing. He left the car for a while; after returning, they drove to Truro.
- Deborah Lamb (February 12, 1977; aged 20)Deborah was hitchhiking on West Terrace when picked up. They drove to Port Gawler where Miller went for his walk. When he returned to the car, Deborah was absent and Worrell was pushing sand into a hole with his foot. Deborah was later found buried at the spot.
- Deborah Skuse (February 19, 1977; killed in the motor accident that claimed Worrell's life)Deborah was the ex-girlfriend of a friend of the pair. After her break-up, Miller and Worrell took her to Mount Gambier for the weekend, but after Worrell got into one of his black moods they decided to return to Adelaide on the Saturday afternoon. Worrell was driving when the car blew a tyre and rolled several times, throwing all three onto the road. Worrell and Deborah died; Miller broke his shoulder blade.
All the murder victims had been strangled, although there was a strong suspicion that the last of them, Deborah Lamb, had been alive when buried.
Criminologist Professor Paul Wilson has suggested that had Worrell not been killed, the Truro murders may have become a much more devastating killing spree, as Worrell was following the "established behavior of some serial killers" with the time between murders getting shorter. Miller himself told Worrell's girlfriend before his arrest that, "It was getting worse lately. It was happening more often. It was perhaps a good thing that Chris died".
Miller stood trial for the murders, and was found guilty of six of the seven murders (with the exception of the first murder, Veronica Knight) on March 12, 1980. Unusually, he was convicted of murder despite having never touched a victim; he was sentenced to the maximum six consecutive terms of life imprisonment.
The testimony at his trial revealed a terrifying story. Miller and Worrell would cruise the city streets every night in Worrell's 1969 blue-and-whiteChrysler Valiant, looking for women that Worrell could have sex with. Worrell was 23, charismatic and good-looking, so Worrell had no trouble in regularly "picking up" local girls for casual sex. Miller would drive Worrell and the woman to a secluded place, where Worrell would have sex with the women, often after tying them up, while Miller waited outside the car. Miller would then drive them back into town and drop them off.
Miller described how the "pick-ups" became more and more terrifying. First, Worrell started occasionally raping the women who refused his advances. Then he started murdering them. Miller was unaware that murder would occur prior to it happening; he stated that it only happened some times and not others. It appeared that as the violence increased, Miller became increasingly fearful of Worrell.
Miller maintained, "They can give me life for knowing about the murders and not reporting them. But they charged me with murder ... It's a load of bullshit". Following the trial one of the jurors hired a lawyer to petition the Attorney-General for a retrial. South Australian Chief Justice Len King agreed that Miller should be granted another hearing on the grounds that the judge at his trial, Mr Justice Matheson, had instructed the jury to find Miller guilty of murder. However, the Attorney-General, Chris Sumner, refused to grant a retrial.
Legally, Miller argued that he never engaged in any murders directly, nor did he explicitly agree prior to going out cruising for women that he would support Worrell in the murders. Nevertheless, he was found guilty of murder because he was found to be a part of a joint criminal enterprise. He was present at the crime scenes and assisted in disposing of the bodies. This created subsequent legal difficulties over the definition of a joint criminal enterprise, but these have largely been resolved on the basis that this was a special—and particularly horrifying—case.
In 1999, Miller applied to have a non-parole period set under new laws, and on February 8, 2000,Chief Justice John Doyle granted a non-parole period of 35 years, making Miller eligible for parole in 2014.
On October 21, 2008, Miller died of terminal cancer, at the age of 68. At that point he was one of the longest-serving prisoners in the state.
