Gertrude Baniszewski facilitated the torture and murder of 16-year-old Sylvia Likens in 1965. Likens was tortured in unspeakable ways for three months by the Baniszewski family while she lived with them. This page has a detailed summary of all of the events (I truly felt sick to my stomach while reading them), which were so horrifying that they're considered "the most terrible crime ever committed in the state of Indiana."
