This installment, 'A Devastating Disappearance', transports us back to December 1984, days before Christmas, when 12-year-old Jonelle Matthews vanished from her home in Greeley, Colorado. Local detectives, shocked by the incident, sought the assistance of the FBI and even garnered the attention of President Ronald Reagan. The dairy industry also played a pivotal role in the search, initiating the practice of printing missing children's photos on milk cartons, bringing the quest for answers into homes across America.
