Monte Rissell and Gene Devier were two real life killers portrayed in the first season of the hit Netflix show Mindhunter. We've profiled most of the other killers portrayed on the show and wanted to talk about these two as well. But, these are lesser known killers whose crimes didn't receive that much coverage so we're profiling them both in one episode.

Join Mike and Gibby as they discuss the life and crimes of these killers. Monte Rissell's crime started extremely young and he began murdering by age 18. FBI profilers studied him while he was in prison. Devier became fixated on 12-year-old Mary Frances Stoner while working on her street as a tree trimmer. Hi fascination turned to murder and it took the help of the FBI to bring him down.
