It was never really explained whether this was a tipping point for Zack, but on October 5, 2006, he made a decision that would change the course of his and Addie’s lives forever. While Addie was in the shower in their bathroom, Zack decided to strangle her to death, after which, he cut her body into various pieces. But it was what he did after that, that had left many people in utter shock.
