A SPECIAL EDITION OF '20/20' INVESTIGATES THE DEATH OF A NEW MOTHER WHO DIED OF A MYSTERIOUS DRUG OVERDOSE AFTER SHE ATE A BOWL OF CEREAL

Episode Airs on Tuesday, Nov. 29, at 9 p.m. EST on ABC

Christina Harris was a new mother who went to sleep and never woke up. Authorities ruled her death an accident until the medical examiner found a lethal amount of heroin in her system. Her friends and family couldn't believe it as they had never known Christina to be a drug user, but there were no fingerprints or evidence of a crime. As far as anyone knew, Christina had simply eaten a bowl of cereal and gone to bed. This episode of "20/20" details how an innocent bedtime snack led to Christina's tragic death. "Cold to the Touch" airs on Tuesday, Nov. 29 (9:00-10:00 p.m. EST), on ABC and streams the next day on Hulu.
