'He may be a prisoner': Theo Hayez's parents believe he is still alive and could have joined a commune - as they slam Belgian police for giving up on the search too soon
- Theo Hayez parents believe he is still alive and could be living in a commune
- They told local media they will not give up hope unless they see his body
- A forensic psychologist said he believed Theo was the victim of a serial killer
The parents of a Belgian backpacker who disappeared in Byron Bay almost two months ago refuse to give up hope the teenager is still alive.
Laurent Hayez and Vinciane Delforge told local media they believe their son may be alive and living in a commune on the New South Wales north coast.
Theo, an 18-year-old backpacker, was last seen leaving the Cheeky Monkey's hotel in the seaside town on May 31 about 11 p.m.
He was on the last leg of a backpacking trip around Australia when he disappeared.

Theo's parents travelled to Australia to assist with the search, but it was officially called off after more than a month of searching failed to find any trace.
Australian police confessed the case was 'baffling'.
But Mr Hayez and Ms Delforge hold out hope there is a less sinister explanation to their son's disappearance.
'As long as there is no body, we will keep hoping,' they said.
'There is a history of bad communities in the neighbourhood, there are people who live in communes. Theo could have enrolled in one.
'He could have been kidnapped, drugged.
'He may be a prisoner somewhere where there is no electricity. That is our hope. Let him be a prisoner and let him be delivered to us.'

Locals have refused to give up hope despite police calling off the official search
A bush camp was located in the same area where Theo's mobile phone 'pinged' on a communications tower at 1:40am on June 1st - just hours after he was last seen.
A Dutch newspaper reported locals stumbled across the campsite while searching for Theo.
While his family never specified whether they believe he is living in that commune, it lends to their theory there may be more in the region - and that Theo could be hidden within one.
'Retreats' tucked away in the Byron Bay hinterland offering spiritual awakenings, meditation and new beginnings have also been found.
While many are what they appear, some people have claimed others are more of an 'unsettling place' - where people give up their old lives to immerse themselves in a new culture with bizarre rituals.

Police combed through dense bushland in Byron Bay and near the lighthouse, but confess there is much land they still have not been able to cover
But Mr Hayez and Ms Delforge said searching for their son in the unforgiving Australian terrain was 'like looking for a needle in a haystack'.
'It is not the Belgian Ardennes,' they explained.
'The vegetation is very dense and the fauna hostile with snakes... but every day we followed the steps Theo could have taken.'
'We were looking for clues. We were just two people among lots of volunteers who were all looking for our son. It was like he was their son too.'
'The land is huge and they know it requires teamwork. Some have grown up in Byron and know the bushes others just wanted to help,' Mr Hayez said.
The pair said while Australian officers had done an incredible job throwing all their resources behind finding Theo, it had been impossible to search everywhere.

'The Australian police have put extraordinary search capabilities in,' Mr Hayez said.
'There were helicopters, drones, dogs, trackers, divers, and even rock climbers to go on the cliffs, but when we left, there were still many unseen areas.'
Three Belgian police officers, including one from a missing persons unit, joined the search for Theo at the end of June for five days.
'The collaboration between the Australian and Belgian police was optimal,' Ms Delforge admitted.
'But five days is too short.'
Theo's parents said Belgian police were under pressure to leave from their superiors.
'When they left they said they would continue the investigation hand in hand with the Australians,' Mr Hayez said.
'A lot of possibilities remain open, given the place and the population.'
The parents' appeal comes just a day after a top forensic psychologist in Australia said he believed Theo may have been the victim of a serial killer.
Tim Watson-Munro says police shouldn't rule out the possibility Theo as well as French tourist Erwan Ferrieux and his British friend Hugo Palmer, both 20, were the victims of murder.
'You cannot discount the fact that you have three young men of very similar profiles who have gone missing or are dead from two coastal towns which in the scheme of Australia's geography are quite close,' he told Daily Mail Australia.
'You've got three vulnerable, trusting backpackers and they've just disappeared without a trace.
'I'm not saying its categorically the work of a serial killer, but its one hell of a coincidence.'

He said he firmly believes their disappearances and presumed deaths could be linked.
'We've got three backpackers who all looked similar, were around the same age and disappeared in similar circumstances,' Mr Watson-Munro said.
He said none of the three young men had any known psychological issues that would suggest they wanted to end their lives or disappear, further lending to the belief they fell victim to foul play.
'I know the three disappearances could easily be misadventure, and I am not saying they are definitely the work of a serial killer, but I have learnt that nothing can or should ever be discounted,'' he said.
He said statistically, the odds of three backpackers going missing in such a short time span in nearby regions was unlikely.
Mr Watson-Munro also argued that from his experience, serial killers generally opted to prey on vulnerable people who may not necessarily be identified as missing immediately.
'I don't want to to be over dramatic or start fear on the eastern seaboard but there is no doubt there are serial killers in our midst.'
