15. Shelly Knotek

Rabbit Hole Happy Hour

This is the devastating and unbelievable story of a monster named Shelly Knotek. A mother who somehow managed to hide decades of abuse. A mother who would be called a serial killer, a psychopath, master manipulator, and a sadist. This story gained attention when Shelly's three daughters reached out to true crime author, Gregg Olsen, wanting to share their story to bring awareness to their mother's patterns and behavior. Why? Because Shelly Knotek will be released from prison in less than a month (June 2022). Gregg Olsen's If You Tell was released in November of 2019 and serves as a story of survival and a warning to all about the monster who will soon be rejoining society.
