He might have been victim of physical violence when he was a child but I believe he grew to be a willing participant in these sick activities with his dad. They were in it together! It was their sick bonding experience like the " how to sexually assault women " bonding sessions he mentioned he used to have with his dad. My money is on the fact that, with the advancement in DNA he knew it was only a matter of time before the murder would tie back to him because he did participate in the killing of that women if not more. Over the last few years we have seen the apprehension of killers in their dotage years ,who had gotten comfortable and thought they had gotten away with murder. It is very suspicious that he only spoke up after the death of his father and decades and decades later after the father committed those crimes. Coupled with the fact that he never told a single living soul including his wife. Let that sink in. Dead men tell no tales and he knew this was his one and only opportunity to spin the tale the way he wanted. That was very clever of him to bring the crime to the police first before they themselves found her remains. In the police recordings he also confessed to have lit that woman of fire and yet in the episode he had initially stated that his father is the one who did everything and all he did was either watch or turn his head away. In one sentence he claimed his father was so cruel and wanted to kill him next and yet the father somehow cared enough not to make his son watch while he shot his Mrs and burned her. Like make it make sense. This dude can't even keep up with his lies. He did this crime with his dad. I have never seen someone who had that many chances to step up and be a decent human being and somehow squashed each and every opportunity. This whole "seeing her ghost" story is what made him finally call the police is absolute malarkey. That audio of the interview is chilling as hell. For someone who supposedly moved on to greener pastures and became a family man, he was awfully cold and cavalier about his role in the torture of those women. I would watch this one if I were you. Crocodile tears!
