Tattarisuo case

[4] Finnish Freemasons, Oddfellows and the members of the Ruusu-Risti [fi] organization were suspected, owing to a local belief that they allegedly used human body parts in rituals.

[5][2] Although these organizations were ultimately found to be innocent, the controversy stirred by the case led to the Freemasons being excluded from the Finnish Officers' Union [fi].

[7] The perpetrators behind the mutilations were the locally well-known driver Vilho Kallio, also known as Noita-Kallio ('Kallio the Witch'), who lived at Hämeentie 72 in Helsinki, along with port workers Ville Saari and Johan Ilmari Hedman, and a couple of women.

In doing so, they believed they would acquire knowledge and powers from the spirits to cure diseases, recover stolen property, and achieve similar objectives.

[10][2] Finnish thriller writer Aarne Haapakoski's debut work Mustalais-suon arvoitus (1931) and Aki Ollikainen's novel Musta satu (2015) are based on the Tattarisuo case.
