Lori Hacking was reported missing on July 19, 2004. According to her husband, Mark, she woke at 5:30 a.m. and drove from her home in Salt Lake City to a local park where she liked to jog. Mark said he was expecting Lori, who was five weeks pregnant, to wake him on her return, but the 27-year-old never came back and never showed up for work.
On July 24, 2004, Mark Hacking told his brothers that he murdered his pregnant wife Lori because she caught him in a lie. He had told her so many lies that admitting to one would have unraveled his tapestry of deceit. In the end it was easier to kill her than to face her.
