Police are staying tight-lipped about their investigation into missing campers who were allegedly murdered by a Jetstar pilot because they want to keep a second crime scene from being 'contaminated'.
Greg Lynn, 55, appeared in court on Friday after being charged with the alleged murder of lovers Richard Hill and Carol Clay following a 20-month investigation.
Forensic officers have ramped up their search for the remains of Mr Hill and Ms Clay after a crime scene was established in Victoria's Great Alpine region on Thursday.
Police are keeping the exact crime scene location a secret, citing significant community and media interest.
Missing Persons Network chief executive Valentine Smith says police have a valid reason why they're keeping the location under wraps.

'They don't want it contaminated, they don't want anything interfered with,' he told the Today show on Friday.
'They certainly wouldn't want to be subconsciously or consciously distracted by other people sort of trying to get a look at what is going on there. They need to protect it.'
He added tracking down the missing silver and blue-coloured trailer with off road wheels which was attached to a blue four-wheel-drive last seen at the campsite the couple vanished from, will be vital.
'I see that the police are really pushing that,' Mr Smith said.
'Without speculating on that as well, obviously of some evidentiary importance to them and may become another crime scene of some sort, depending on what they are looking for.'
Police are preparing for the dangerous task of entering the rugged Victorian wilderness yet again in the hope of finally locating the missing bodies of Mr Hill and Mrs Clay.
Victorian Police Assistant Commissioner Bob Hill said police had been provided 'specific' information as to where to find the burial site within the Great Alpine region.

But even with detailed information on a burial site, police have said it will take days to prepare for the dig in what is some of the most rugged terrain on the planet.
Last night, Assistant Commissioner Hill stole the spotlight from Detective Inspector Andrew Stamper, who has tirelessly led the investigation for near on two years.
'This morning detectives identified a crime scene within the Great Alpine area and forensic specialists will commence searching at that location over the coming days,' Assistant Commissioner Hill told reporters.
'We have located a specific area and we will establish a search parameter.
'Police are hopeful we will be able to locate the deceased in order to find closure for the families.'
While the search is taking place in remote bushland, forensic specialists will also be scouring Lynn's two-storey home in Melbourne's west.
Ground-penetrating radar which can uncover anomalies deep within the earth or even concrete structures will be brought to assist the evidence gathering operation.
