Law & Order: Special Victims Unit
Martin Schultz worked as a camp counselor for young boys for over 40 years.
When a janitor named Johnny Dubcek is arrested for brutally attacking a gymnastics coach, the SVU squad connects Dubcek's violent behavior to being sexually abused by Schultz while attending his camp.
It is later revealed that Schultz sexually abused numerous boys from his camp and some of them ended up becoming criminals themselves as they reached adulthood, including a man named Reggie Rhodes (who was on death row).
After the SVU detectives discover that Schultz kept tapes of the abuse, he is arrested for possession of child pornography & reckless endangerment. At the end of the episode, it is shown that Schultz is placed in the same cell block as Johnny Dubcek.
A sociopathic pedophile, Schultz is adept at sizing up his victims' weaknesses and exploiting them for his own gain. He becomes a father figure to them and made them feel responsible for the abuse that he inflicted on them.
Many of his victims were so traumatized by his abuse that they ended up became violent criminals themselves as they became adults.
