Two-year-old Corey Edkin disappeared from his central Pennsylvania home in October 1986 and is still missing. His grandmother, Myrle Rovenolt, was accused of poisoning his grandfather two months later, and this past summer she was sentenced to life in prison for the poisoning death of her third husband.  Corey and Myrle have connections to three other local cold cases – two homicides, and one disappearance presumed homicide – and that’s why we’re diving into the first of three episodescovering them. We’ll attempt to detangle an extensive web of information and get closer to a resolution nearly 40 years later.
