I am not convinced the park/river are where police should be looking though, i think the real location of the attack is a lot closer to home, round the back of Libby’s house
There were reports of a loud scream from the back of the houses and a noise of a gate banging, I think that area is far more likely than the park
I believe that PR probably took her home, and that she got home and realised she had no keys so went round the back of the property and PR then followed her and pounced or PR told her he would break into the house for her (he would know how to) and they both went round the back and he attacked her by the gate to Libby’s
Much quieter, less chance of being disturbed, whereas the park would have people around given it was a dogging area and you would have druggies and chavs hanging around
