Episode Details

In June 1973, seven-year-old Susie Joerger was kidnapped from her family’s tent at a Montana campground, sparking one of the largest searches in the state's history. Despite efforts by the FBI and local deputies, investigators struggled with few clues until the discovery of another victim, Sandra Smalligan, led them toward local contractor David Masterson. Though Masterson initially passed polygraph tests, federal profilers correctly predicted he would contact the family, leading to a series of recorded phone calls with Susie’s mother, Marietta. Her unwavering determination and compassionate dialogue eventually caused the suspect to incriminate himself, revealing his identity as the perpetrator. Following his arrest, a grizzly search of his property uncovered physical trophies and remains of multiple victims. Masterson ultimately confessed to four murders before taking his own life in jail to avoid trial.
