The Object of Murder

In 2016, 33-year-old Tricia Todd was reported missing after failing to pick up her daughter from a babysitter. As her family hoped and prayed, investigators found her online journal that revealed the true horror of what had happened.

In 1982, 35-year-old JoAnn Tate was stabbed to death in her home in St Louis. Her kids Melissa, 7, and Renee, 4, nearly died. JoAnn's diary revealed a man Melissa ID'd as the attacker. Years later, new memories emerged that changed everyone's lives.

In 2000, 31-year-old Mike Williams vanished while duck hunting on a Florida lake. His boat and his shotgun were found, but not his body. Seventeen years later, a violent kidnapping led detectives to suspects who had been there all along.

In 2011, Holly Bobo is abducted from her home in rural Tennessee; the investigation goes cold for two years until a hunter makes a gruesome discovery.

In 2014, 57-year-old Nancy Pfister was discovered beaten to death in her closet in her Aspen, CO home. When items of Nancy's were found, including the key to the closet where her body was found, investigators zeroed in on who was responsible.

Michelle Mockbee, 42, is beaten to death at work; robbery is ruled out since Mockbee is still wearing her pink sapphire ring; the case stalls until a video surfaces that blows it wide open.
