Also if she had 'staged' her disappearance, leaving her dog loose not even tying her to the bench (highly doubtful) surely after seeing the massive publicity, distress of her parents on the news, her DP saying her DC were hysterical and seeing the massive police resources that have gone into finding her, she'd have at least contacted someone to say she was OK. Even the police themselves, There's just no way anyone would have let this go on for this long.
She could easily have 'disappeared' while pretending to go to work or the shops leaving the dog at home.
I wonder if the police have done reconstruction of someone carrying someone of her size off from the area she was last seen in and how long it would take them to get to an area where a vehicle could have been left, what tree cover there would have been, assuming they've thoroughly checked every inch of land in the vicinity where she could have been left.
The caravan park - assume they checked every caravan on the day she disappeared. Guests who left that day etc.
Not overly invested just such a weird, upsetting case and just hope for her family's sake it doesn't turn into one where there are no answers and she's never found which is worse that the alternative IMO. Couldn't imagine it if it was my adult DD especially if I feared she been abducted and could still be alive, or was alive for a while afterwards but wasn't found in time.
