While the conflicting reports about how and where the phone and harness etc were found are confusing, I still think it is more likely than not she has simple fallen in the water, I am sad to say.
If the police thought there was any reason to believe Nicola could have deliberately gone missing, we would have surely have had some manner of appeal directed at her
And if they thought there was a likelihood of third party involvement, you would have thought they would be casting a wider net with regard to asking people to report anything suspicious.
But they aren’t doing either of these things.
Which is upsetting because either of those alternatives offers a small shred of hope, while the more simple explanation that she has fallen in the river does not.
