Less likely surely? Given the number of sightings prior to the bench there would surely have been more had she continued to walk a further mile along the river?!
I've started to look at this differently and now I'm working on which is the least unlikely theory and I'd welcome people adding to what I've come up with.
Arguments against accident at bench
She knows the danger of deep water there
Willow is the only springer with an aversion to going into water after their owner
If she died instantly her body would be there
If she tried getting out she'd go under and not get over the weir
Why did people finding willow not see her in the water
Arguments against suicide somewhere along the river
How did willow not follow her
Would she really leave her family and dog like this
Why would nobody see her crossing the road
Arguments against being shoved in the water and dying acvidentally
How did they get the body out
Where did they store her
Would anyone run the risk of returning the body to the river
Phone tracking would put them at risk
Conclusion none of it makes sense and there's another scenario I can't think of.
