The case of Steven Pladl and Katie Fusco/Pladl is as twisted as it is tragic. After living with her adoptive parents Anthony and Kelly Fusco, Katie Fusco (originally named Denise Pladl) reunited with her biological father Steven Pladl, where they soon began a sexual relationship, which later resulted in the birth of their son, Bennett. Two years later, their tumultuous affair would leave Katie, Bennett, Anthony and Steven dead. Savannah explores this disturbing tale and the many twists and turns that led to this tragedy.
