Awful news, but at least there is some closure, and hopefully the police will find out what happened.
My thoughts are that it’s incredibly lucky that they found her in the Humber, as it’s huge in that area. Thinking about the Sala plane crash, and how long it took to find the wreckage even though they knew a rough area and were actively looking there.
I’m no expert, but I’d be hugely surprised if she could have been carried all the way from the river at Oak Road. It’s narrow, long, windy and muddy, and its not exactly the fastest flowing river- it doesn’t seem right to me.
