But as Mark and Lori were preparing for their big move, their dream life suddenly turned into a nightmare. Shockingly, it was revealed that Mark was living a complete lie, and none of his achievements were real. When confronted with the truth, he took matters into his own hands by shooting Lori and disposing of her body, lying to authorities, and leaving countless unanswered questions. What pushed him over the edge to commit this crime, and what was his true motive?
