Rachel Morin's mom shares the detective's advice that kept her going before her daughter's killer was caught

Patty Morin, mother of Rachel Morin, shared how a detective's advice to 'have hope' helped her during her daughter's eight-month murder investigation, which led to the arrest of Victor Martinez-Hernandez. She now offers similar encouragement to the family of 84-year-old Nancy Guthrie, whose abduction remains unsolved, as investigators work on DNA samples with potential delays.
