I don't think she fell in the water. They did extensive searches with a diving team and equipment, also the river is very still in that area so her body would be unlikely to move quickly down stream.
I have not posted on the threads so far. I find the whole speculation and I'll-informed views incredibly distasteful.
I'm just commenting on this post, and others like it. I can understand people being surprised Nicola hasn't been found, if she fell in the river.
A son of a close friend died in similar tragic circumstances in a European country. He was seen on CCTV returning from a night out to a certain point, very close to home. They searched the nearby water, a canal, extensively. Sadly it was 7 weeks before his body was recovered. In that time his family explored every other option you could imagine. The effort put in by the family, police & friends was enormous. He was found almost exactly where he'd gone missing. For no very clear reason, just the height of the water, his body was not found in the previous searches.
Of course it is possible that poor Nicola fell in & drowned & yet her body has not been recovered. That is almost definitely what happened but sadly it may be some time before this is confirmed.
My deepest sympathies are with Nicola's family & friends 💔
