12. Interview with a Serial Killer

In 1972, Arthur John Shawcross raped and murdered an ten-year-old boy and an eight-year-old girl. When he was caught, he confessed to the killings. However, thanks to some legal trickery, he was actually released from prison 12 years later. At that point, Shawcross embarked on a killing spree that earned him the nickname the Genesee River Killer. This 2003 documentary takes viewers on a blow-by-blow tour of Shawcross’ insanity, including his predilection toward cannibalism.
