I would be inclined to agree with them given all the facts.
A couple things stand out from the night before she disappeared:
- She went to visit someone, and it was later discovered she'd lied about who it was she had gone to see, and so far police and family have not been able to ascertain where she went or who she met, I believe it was for about 45mins to an hour she was gone.
- Leah turned off the location settings on her phone so her whereabouts could not be seen, the phone company said she'd never done this before.
Whatever was going on that evening must be directly linked to whatever has happened to her, it's frustrating that the 'crying girl by the lake' sighting doesn't appear to have been confirmed or ruled out as Leah (unless I've missed something, apologies if so), however it seems that particular sighting raises more questions than answers, particularly how she could have been using a phone when the provider maintains her phone has not been used since 8am that day and the sightings were at 10/11am. So why on earth would she have a secret one?
Could Leah have been involved in something illicit that was big enough that someone would cause her to disappear over it?
Could Leah have been the victim of an entirely random attack by a predator?
Could Leah have decided to run away in the heat of the moment, not packing or preparing beforehand and potentially with financial/practical assistance from a third party? And stay hidden all this time?
All just my own musings. So very much hoping for a positive outcome for Leah's poor family!
