The lack of sightings of RW travelling to LO's house that Thursday would suggest that she didn't walk/use public transport but had a lift in someone's car, or never left her own house alive. (We have no reason to disbelieve that AG witnessed her returning to her home that morning, so any Wednesday demise theories are out of the question). I'd be really interested to know who was in the house that Thursday morning.
IF NM really was one of those present in RW's house on that Thursday, then it's quite possible that RW left the house and NM made his excuses, like he had to go run some errands, and left very shortly afterwards, stopping to pick her up. The word 'kidnap', used by the LE is playing with my mind; nobody 'kidnaps' a corpse do they? So does that mean she left the house alive but signs of a struggle/attack (blood) were found in the car? - she might have been taken and met her end someplace else, rather than being killed at home. NM could have popped back to RW's house later, even when his mum was back from her appointment, (RW wasn't a missing person at that time), made an excuse to use the bathroom and removed the laptop/tablet (teens always have their phone with them, so this would be with RW already). There might have been a previous exchange between NM and RW, via text/social media messaging, that NM needed to delete to distance himself (imo, teenagers lock their phones with a password, so their phones can not be used by others except to be switched off, whereas there's a chance they are still logged into social media on their laptops/tablets).
Just my own thoughts.
