13. Albert Fish: In Sin He Found Salvation

IMDb Rating: 5.8
Available On: Amazon Prime

This documentary tells the story of American serial killer named Albert Fish, who was also a child rapist and cannibal. Although only five murders were connected to him, the number of his victims is probably higher. At one point, Fish even claimed that the real number of his victims was close to 100. He was executed in 1936 by electric chair. To give better insight into Fish’s crimes, the documentary uses archival footage, interviews, and scene recreations.
