The Tattarisuo case, a Finnish criminal investigation from the 1930s, took place in the Tattarisuo area, then part of the rural outskirts of Helsinki. The investigation, which spanned about a year, eventually revealed that a small local group engaged in black magic was responsible for the crime. Some members of the group had stolen human remains from the Malmi Cemetery and used them in rituals conducted at a spring in Tattarisuo and its surrounding area. The case remains one of the most infamous in Finnish criminal history due to its connection with grave robbery and occult rituals.
