This has haunted me as well. I pray I would do the right thing but I would have to have dang hard evidence of it. I think I would first hire an attorney to guide me and let him handle the LE notification. Golly what a horrible position that would be. I think the guilt of not doing the right thing would destroy me and certainly would end up destroying any relationship I had with that child. Let's face it any child that would kill 2 innocent people is not going on to have a good life like we so all wish for our children.
