Yes welcome and great first post, Myjamfactory.
One of my big concerns since the beginning of this case which has grown over the weeks where Libby has remained unfound, has been the possibility that PR (if the perpetrator) went to his workplace or land/premises nearby that night/early morning. We know that perpetrators nearly always head somewhere familiar as they need to assess the likelihood of being seen/heard committing a crime and if it would be a good place for them to dispose of evidence.
The nature of PR's workplace is disturbing and why I hesitated to mention it but was hoping that as soon as they arrested PR they would be all over it as quickly as possible. One of the first cases I read about was a US family annihilator, Michael Blagg, who murdered his wife and daughter. Police obviously suspected him straight away as the husband, but failed to check his large work dumpster soon enough. They ended up having to track rubbish from his firm to the landfill where fortunately after weeks of hellish recovery work they were able to recover his wife Jennifer's body, although Abby his little daughter has never been found and he isn't telling. This ended up being a significant factor in convicting him, because of the connectivity between his workplace and where her body was located. I remember thinking every detective on that case probably forever had emblazoned in their mind "Check the work dumpsters", "NOW".
And if you look at the Chris Watts case, this is another example of where police made this link very quickly and so found Shannan and her daughters.
In Blagg's case, colleagues also remembered him on that day throwing loads of rubbish into the work dumpster (to cover the body) whereas previously he never went there. Hopefully police were able to question colleagues whether PR was doing anything unusual, throwing things away after that night. And if he "borrowed" anything from there, eg plastic sheeting, knives etc.
When you think about it, advances in DNA and autopsy techniques have and will motivate murderers much more to conceal bodies. So we can expect that more will try and use bodies of water, drive longer distances, or try and get the bodies into waste disposal systems or sites. In some (usually US cases, where a person goes missing near vast areas of wilderness, it is much harder to search) but people who disappear in urban UK towns should be found, so to me this strongly indicates deliberate concealment and therefore foul play.
Water sources of course complicate this, especially those that lead out to the sea, but I don't find the theory that Libby ended up in water accidentally very credible. Everyone on WS knows the young male + alcohol + body of water pattern that is horribly predictable but I think this is the vulnerable woman + meets predator = disappears pattern which is also horribly predictable. I only hope Libby's suffering was short and that her family and friends get answers.
I too, like others cling on to the hope that this case is one of those rare ones that defy the odds, it's always possible.
I also hope that the police are just taking time to build a strong case. They had the luxury of time, due to the other charges against PR, which they don't always have. They should have tonnes of info about him and his movements. They likely have a slew of











and internet searches to go through which will tell them a lot about him and his fantasies and plans (and I don't mean his summer holidays). Predators sometimes write detailed plans/research.
I imagine police's strategy has been to just try and disprove everything he has said he did that night/morning. If he repeatedly changed his story when he or his car was caught on CCTV when he said he was elsewhere (and eg Libby can't be picked up on CCTV where he said he left her) then I think they will charge him eventually, hopefully with some physical evidence. And break any false alibis he or someone close to him may have given. Almost certainly this type of predator will keep something of the victim's so they can relive the crime. Hopefully if guilty, PR did not have time to clear things from his home before he went into custody and maybe they have already found something to connect him to Libby.
