If KAM and JJ were a couple and have an 8 month old baby girl, then she may know 'of' her and aided JJ for whatever reason. CM told her family she was done with JJ in March, 2014...that's about the same time the baby would've been born. One would wonder why KAM and JJ would want to go to such lengths, she couldn't have been any sort of threat to them? Why not just go away and get on with your lives? No reason to murder her. What possible motive could there be for this? Maybe CM knew something that JJ wanted kept quiet...who knows? It's an awful waste of a young life, and now a little boy, a brother and parents have no mother, sister and daughter. So very, very sad.
