Police will only release info they want in the public domain.
Only seen twice in fields according to info in BBC article over 23mins, so on the face of it, sounds like she could have been approached by someone without anyone seeing.
The whole thing about her found mobile being on a works call when found on bench raises questions. You would think she would say something to colleague(s) if she was just going to put her mobile down to do something. But then unless her mobile's mic was muted, surely anything untoward happening would be heard by her colleagues.
Hopefully she is found soon, sadly almost certainly dead, and there is no sign of others being involved.
Already covered. She joined her teams call muted, then XYZ happened, and she remained connected to the teams call after the meeting had finished.
It would sound reasonable that she might have been on the call sitting on the bench when the ball went into the river and she just nipped down to retrieve it and fell in.
However, on seeing how shallow the river looks, and how calm it is, and the fact that there is a sort of weir just down river from the bend she was on the bench on, it seems odd that she would not have been found, washed up, or floated up to the surface somewhere.
It's another possibility the police know something more and are keeping it to themselves, very common for police to do this, as we have seen from the Kohlberger case in the US where they were being criticised by public know-it-alls, but all the time were tracking their man and building evidence.
I've had a look at the scene, and I've no idea how you could snatch a woman on a popular dog walkers path, and get her out of there in broad daylight without anyone noticing.
It's all so curious, and very interesting, but to me right now the dogs ball going into the river and her thinking she could just nip down and get it and go right back to the teams meeting SEEMS the most likely to me. A pure guess of course!
