In the discovery we found out that he told his family that he had finally come around to their way of thinking about Shanann and was divorcing her.
This was because he had already made the decision to murder his family and thought they would back up his evil idiotic plan.
His spiteful family was thrilled when they thought he was going to leave his pregnant wife and little girls.
His fans/family are still repeating those same lies about Shanann, thinking people are going to believe them, just like the stupid monster thought people would believe his plan to make people think that his shady wife took his beloved daughters, never to be seen again.
