It's one of every new mother's greatest fears. You put your child down for a nap, only to later notice muffled cries coming from the bedroom. What happened next lands Tammy Wynne Marquardt in jail for nearly 14 years and will haunt her for the rest of her life. Reporter Mark Carcasole shares Tammy's harrowing story and learns more about the man whose testimony, she says, destroyed her life.

In May 1991, 34-year-old Yvonne Rouleau was tortured and murdered at the Nozzles Gas Bar where the mother of three worked in Kingston, Ontario. But the horror didn't start there. Reporter Caryn Lieberman travels to Kingston to hear from the families and survivors reclaiming their voices in order to tell this story and to learn how the investigation into Rouleau's case led detectives to a series of other horrific attacks targeting some of the most vulnerable members of the community, the full details of which took decades to come to light.
