In April 1998, a public servant from
Cottesloe, Lance Williams (aged 41), was identified by police as the prime suspect, after his behaviour attracted their attention (e.g. driving around after midnight and circling the Claremont area up to 30 times) during a decoy operation. Williams died in 2018. although Murdoch was serving a custodial sentence from November 1995 until February 1997. In October 2006, it was also announced that British murderer
Mark Dixie was a prime suspect in the killings, and that Macro had requested DNA samples. However, Western Australia Police Deputy Commissioner Murray Lampard was later quoted as saying: "Dixie was closely investigated at the time and eventually ruled out as a suspect." On 22 December 2016, Bradley Robert Edwards was arrested at his
Kewdale house in relation to the deaths of both Jane and Ciara. The next day, he was charged with both murders. According to
ABC News, he is believed to have had no previous link to the case, though he had pleaded guilty to the aggravated assault of a social worker at
Hollywood Private Hospital on 7 May 1990. He was also charged in relation to two other attacks: the house break-and-enter and unlawful detention of an 18-year-old woman in
Huntingdale on 15 February 1988 (where a stolen kimono with his DNA was dropped as the attacker fled), and the unlawful detention and two counts of aggravated sexual penetration without consent of a 17-year-old girl in Claremont on 12 February 1995. On 22 February 2018, Edwards was also charged with the wilful murder of the first victim, Sarah Spiers. In all, Edwards was charged with eight offences, and on 21 October 2019, Edwards pleaded guilty to the five non-murder charges (at Huntingdale and at
Karrakatta Cemetery).
Trial Before the trial, the prosecution applied for Edwards to be
tried by judge alone without a jury. The application was granted due to the publicity surrounding the case and the graphic nature of the evidence. The murder trial began on 25 November 2019, before Supreme Court Justice
Stephen Hall. During the trial, the court was told that two of the victims had defensive wounds. Edwards' DNA was also found under Glennon's fingernails (and matched to the kimono) although the defence argued this evidence was contaminated in the laboratory. Between April 1996 and December 1998, Edwards drove a white VS Series wagon with Telstra logos. The vehicle was tracked down and impounded on the same day as his arrest. During the hearing, it was revealed that fibres matching carpet in the rear of Edwards' vehicle matched fibres found on the bodies of both Rimmer and Glennon On 23 December 2020, Edwards was sentenced to life imprisonment with the possibility of a parole after 40 years. Hall said there was a "high likelihood" that Edwards would die in prison. ==Possible related cases==
