Police in northern Australia fear that a 79-year-old woman may have been attacked by crocodiles after what are believed to be human remains were found near a creek infested with the unsafe reptiles.
Anne Cameron, 79, disappeared from a Port Douglas nursing home on Tuesday, with police unable to rule out the possibility she had been attacked by a crocodile after wandering down to a nearby river.
Police later found clothing, a walking stick with her name and human remains beside a crocodile-infested creek near Four Mile Beach, about a mile from the aged care facility.
"We strongly suspect now that there has been involvement of a crocodile attack", Acting Inspector Ed Lukin said.
Police believe Anne Cameron, 79, became disorientated after leaving her aged care facility in Port Douglas, north Queensland, and wandered into dense mangroves.
The human remains are undergoing forensic testing.
Her daughter Isabella Eggins, who has helped police and SES with the three-day search, admitted the family were convinced Ms Cameron was eaten alive.
Wildlife officers are expected to set traps to catch the crocodile believed to have taken Ms Cameron.
"We still hold our hope that we will find this missing person alive, of course as the days progress that option will diminish, and as time goes by we will continue to reassess our searching options".
"Those items are now being tested in Cairns and we expect to see results tonight or tomorrow".
Surveillance will be conducted on water and on foot on Thursday night.
She had only recently moved to the aged care facility after relocating from Canberra and family were involved in the search since her disappearance on Tuesday afternoon.
It is feared that Canberra woman Anne Cameron has been killed by crocodiles in far north Queensland.
