Wesley Shermantine: The Speed Freak Killer – Rage, Meth, and the Wells of Death

In this chilling episode of Among Monsters, host Damien Vale takes you deep into the terrifying case of Wesley Shermantine, one half of California’s infamous Speed Freak Killers. With charm masking sadism and methamphetamine fueling his rage, Shermantine, alongside partner Loren Herzog, hunted the Central Valley for years — murdering, raping, and discarding victims in abandoned wells, orchards, and fields. Even after being sentenced to death in 2001, Shermantine continued to wield control from behind bars — exchanging hand-drawn maps of burial sites for cash, revealing long-forgotten horrors beneath California’s farmland. This episode exposes the disturbing psychology and twisted legacy of a killer who treated murder like sport and the dead like trophies.
