Police believe human remains found in a nature reserve in Western Australia's Wheatbelt region are those of murder victim Wade Dunn.
The remains, which are yet to be formally identified, were found by police on Monday in a remote area of the Udumung Nature Reserve in Wannamal.
Homicide detectives and forensics officers are on the scene about 115km northeast of Perth, WA Police said on Tuesday.
Drug dealer Gary David Jackson and his cousin Mark David Corbett beat Mr Dunn with a metal pole after luring him to Corbett's Alexander Heights home in May 2015.
Mr Dunn, a 40-year-old father of three, was dismembered with a chainsaw and his head was kept in Jackson's ute for days.
Corbett and Jackson were each convicted of murder but Mr Dunn's remains, which were dumped in different locations northeast of Perth, were never found.
Jackson was jailed for life with a minimum of 22 years. He launched an appeal against his conviction which was rejected in 2018.
Corbett is also serving a life sentence and will spend at least 13 years behind bars.
The WA Supreme Court previously heard Mr Dunn was lured to the house and bashed and his killers then tried to cover their tracks by bleaching the inside of the house.
Justice Jeremy Allanson told Jackson at the time of sentencing the way the body was dealt with and disposed of magnified the hurt to Mr Dunn's family.
Labor introduced "no body, no parole" legislation in 2018, denying the possibility of early release to killers who refuse to disclose the location of their victims' remains.
