**Special Edition**
On February 17, 2025, firefighters in Connecticut arrived at a home in Waterbury in response to a 911 call from Kimberly Sullivan. She told dispatchers that her step-son was inside and that he needed an ambulance. The firefighters were unprepared for the GRIMM discovery within. Kimberly's step-son had collapsed in the house, but it was clear that he was suffering from more than just smoke inhalation, as he was skeletal, dirty and disheveled. In this special episode of GRIMM, Marina covers the unfathomable details surrounding the rescue of 32-year-old "John Doe," after an alleged 20 years behind a door locked by his own family.
