Carl Dunford is the kidnapper and rapist of preteen Britney Dunlap, who was held captive for five years in a cell under Dunford's garage. Signs of Dunford's pedophilia also showed in stashes of child porn, which ex-wife Debra Hartnell removed when she burglarized the house. Dunlap eventually developed Stockholm syndrome from the captivity and torture.
When Dunford was no longer aroused from Dunlap aging, he tried to get her to kidnap another girl around the age she was when she was abducted. Instead, she stabbed Dunford to death, then castrated him, wrapped his corpse in a tarp, and dumped him in a river. She then ran to her childhood shed in the woods for shelter.
The crime was originally blamed on eco-terrorists and environmental protesters. After further investigation and recovering Dunlap from her hiding place, the investigation was closed. Dunlap was arranged to receive psychiatric treatment instead of face felony charges. (SVU: "Infiltrated")
