Dr. Phil sits down with Amy Hall, who explains how she and her husband, Allen, were blindsided when their 16-year-old son, Jed, vanished from their home in Idaho Falls, Idaho, in January 2018. Amy and Allen say they worked with the police and detectives to find Jed and finally accepted help from volunteers Jared Leisek and Doug Bishop from Adventure with Purpose, a search and recovery dive team who has helped to solve cold cases across the country. Dr. Phil sends a crew to Idaho Falls to follow the mystery of what happened to Jed. Then, retired law enforcement officer Frank Powell shares how regular citizens can help become volunteers to find missing people. And, past guest Mike Knabel, who along with his family has been searching for his daughter Andrea Knabel since she disappeared in August 2019, gives an update.
