I think you're right Indigo, it would be very difficult for a woman to walk away from her own children like that and start a new life, undiscovered. But I also, having walked the route along that alleyway / mini road that Razzell would have taken, can not perceive where such an attack as a violet assault, abduction, and placing a perhaps unconscious or dead person into the boot of a Laguna could have been carried off without someone seeing something. I think she was planning to meet someone she already knew, someone in her own field of work who has both a predisposition to execute his unsuspecting victims and has repeatedly demonstrated a willingness to leave evidence for the police to follow up on. He has identifiably given two specific names to the police and both those unsuspecting suspects discovered what the blind, procedural loving, gullible boys in blue will do to try and get a conviction on them.
