The Keepers
This is a documentary show that revisits the unsolved murder of Cathy Cesnik, a nun that taught English and drama in high school. She went missing in 1969, and it wasn’t until two months later that the police discovered her body. There were no convictions for her murder, and the culprit was never apprehended. The students that Cathy taught believe that her murder was being covered up to protect the priest. In the 90s, one student spoke out about these claims, but the show takes a closer look and tries to solve the mystery. If you’re interested in whodunit shows, this one will keep you at the edge of your seat.
