I find it totally bizarre to read that 'she has a great relationship with her family'. I mean I can understand parents staying in touch, but 'a great relationship'? How do you put what she did 'in a box' and not let it influence you?
I never understood how many victims stay in an abusive relationship or parents who had junky kids lie,cheat and steal from them and others for decades. Parents, eh ok stand by your child during the process is onething but anything after is voluntary, especially with adult children. I think there is a combination of denial and blame game at play here ie they believed their daughter's abuse excuse. I've seen families seperate and split for far less. There are certain lines one does not cross in life and I guess with this family murder is not one of them.
