The prosecutor responsible for convicting Claremont serial killer Bradley Robert Edwards is to take on the case of the disappearance of Mandurah teenager Hayley Dodd.
Deputy director of public prosecutions Carmel Barbagallo led the team of prosecutors which worked for four years to convict Edwards of murdering Ciara Glennon and Jane Rimmer, who vanished less than three years before Hayley.
Ms Barbagallo will lead the prosecution of Francis John Wark, in a trial of the high-profile case due to begin on February 15, 2021.
Then 17-year-old Hayley disappeared in July 1999.
She was last seen alive walking along a road near Badgingarra in WA's Wheatbelt region.
Sixteen years later, in 2015, Mr Wark was charged with abducting and murdering her.
Wark was remanded in custody. He continues to deny the charges.
Justice Michael Corboy will preside in the jury trial.
The Mandurah Mail understands the jury will be taken to key sites in the case - North West Road, where Hayley was last seen, Badgingarra and Moora.
The Supreme Court of Western Australia has confirmed that a new indictment had been filed, charging Mr Wark with murder instead of wilful murder.
Hayley's mother Margaret, who lives in Mandurah, told the Mail yesterday that she was attempting to stay positive.
"I'm trying not to focus on it," Margaret said. "I'll deal with it in February.
"I did not follow the Claremont case whatsoever because it was too upsetting.
"I just cross my fingers and hope we get a good outcome."
She said her children had been affected by the case their whole lives.
"I can stand it but I worry about my children.
"There's no help out there for them."
