West Australian police have searched the former home of convicted killer Francis John Wark in a bid to find the remains of Hayley Dodd.
Special crime detectives and forensic officers on Tuesday searched the property in rural Badgingarra, near where Hayley was last seen in 1999.
"The search relates to the ongoing investigation to locate Hayley Dodd's remains," WA Police said in a brief statement.
"The property was previously occupied by Francis Wark.
"At this time there have been no significant developments and search activity will continue tomorrow."
Wark, 65, was acquitted by a WA Supreme Court jury of murdering Hayley after a six-week retrial but found guilty of the lesser charge of manslaughter.
Justice Stephen Hall last week jailed Wark for 18 years - six years longer than the previous record manslaughter sentence in WA.
Wark will be eligible for parole after serving 16 years but will only be released if he complies with the state's no body, no parole law.
Hayley was 17 when she was last seen alive in 1999, walking along a road near Badgingarra, about 200 kilometres north of Perth.
Her body has never been found.
In his sentencing remarks, Justice Hall found Wark had lured Hayley into his ute with an intention to sexually assault her and had attacked her when she tried to resist.
He then disposed of her body with "callous disregard" in a way that ensured he would not be linked to her death.
Wark was only charged in 2015 after a cold case review linked an earring and a strand of hair found in the ute to Hayley.
Hayley's mother Margaret Dodd welcomed the sentence after earlier appealing directly to Wark to reveal where Hayley's body was left.
Wark has been behind bars since 2007, when he was jailed for raping a woman he picked up in a remote part of Queensland in 2007.
Justice Hall said Wark's offending fell into the worst category for manslaughter given the apparent sexual motivation and Hayley's youth and vulnerability.
"She was a very young woman - no more than a girl, in fact," the judge said.
"At 17, she had her whole life ahead of her."
