S1, E1: Brother and sister, Jerry Sloop and Debra Hall in Marion, IN, have been on a quest to find their half-brother, Michael David Peterson, for almost 40 years. Due to the hospitalization of their mother, the family was forced to part ways. At the age of five and six, Jerry and Debra were sent to stay with their birth father. Michael, two years-old at the time, remained with his birth father, David Peterson. Shortly thereafter, David took Michael to Salt Lake City, UT and no one has seen them since. After several failed attempts to find Michael using private investigators, Jerry and Debra reached out to Troy, as they and their ailing mother are desperate to reconnect with Michael for the first time in almost 40 years.
