Can't see how there can be a positive outcome to this after so long. Two plausible theories, but you'd have thought searches would have found something by now. But then you have to consider how completely incompetent the authorities are in this neck of the woods...
Missing backpacker’s dad disputes Cambodian authorities’ disappearance theory
The father of a British tourist who disappeared on a Cambodian holiday island disputes a police theory she drowned during a post-party swim.
The heartbroken dad of a missing British backpacker on a Cambodian holiday island insists his daughter was snatched, disputing a police theory she drowned on a night-time swim.
Phil Bambridge, the father of missing tourist Amelia Bambridge, has flown to Cambodia to lead the search for his 21-year-old daughter, The Sun reports.
He said he disagreed with police who say she drowned in the early hours of the morning after attending a beach party.
“We were getting conflicting times of when she got there,” Mr Bambridge told Sky News.
“I don’t think she’s in the sea, I think she’s inland somewhere.
“I think someone’s taken her. I don’t think she’s had an accident. If she’d had an accident she would have been found.”
