You've got to be very cold blooded to do whatever you did to CL, dumped the body away from any detection for over a decade now and basically keep your head down while doing your day job or being out and about in York.
But then many killers do that pretty comfortably until something happens and they eventually get caught and there's certainly no chance the police are anywhere near cracking this case as they seemed to be in 2014.
Of course seems likely the whole events involved number of people so not like it's just one person which adds to things. Perhaps it was really an accident, person who was there panicked and got some help and it's remained a pact between them ever since.
Just having a look to see what's going on in the thread given I had fatigue from it a while back with some of the implausible theories, very impressed with the commitment of the same posters from when I joined 18 months back. If NYP had this commitment it could've been cracked by now!
