The Knoxville Nightmare: Christa Pike & The Murder of Coleen Slemmer

·44 min·2 clips

Dental records confirmed the body was 19-year-old Colleen Slimmer.

Unspeakable opens with its usual mature-audience warning and a round of shout-outs before settling into a Knoxville case that is hard to hear but hard to look away from. The story begins with a dead woman in the woods and a scene that immediately tells investigators this is not a simple homicide. Her face is gone. Her body is covered with dirt, twigs, and signs of a violent struggle. The Knox County medical examiner identifies her only as Jane Doe at first, because the damage makes recognition impossible. The autopsy becomes its own horror show. Dr. Sandra Elkins starts cataloging wounds by letter, and the list runs so long that she burns through the alphabet before she can finish describing them. The episode stays with that ugliness instead of skimming past it, which makes clear why the case lodged so hard with the people handling it. Detectives also have to sort through the stranger details around the scene. An inverted star in a circle leads to talk about a possible satanic ritual, and the case briefly picks up that darker speculation. KJ does not leave it there. KJ keeps pulling the story back to what can be proven, what the body shows, and what still needs answering. The narration moves from the scene to the autopsy to the questions the injuries raise, then toward the larger picture of who this woman was. Side notes and shout-outs come first, so the case takes a little while to fully lock in. Once it does, the episode settles into a steady forensic rhythm: geography, timeline, physical evidence, and the growing sense that the truth sits with the people around the missing woman. By the close, the case is still unfolding, but the outline is there, and the listener is left with the sense that the hardest part is untangling what happened and who knew what when.

As heard by us

A grim Unspeakable case built around a Jane Doe, a violent autopsy, and a possible satanic ritual theory.

This Unspeakable episode follows a Jane Doe found in the woods and centers the case on what the autopsy can actually show. The injuries are described plainly and with real weight: many slash and stab wounds, enough to make the killing feel brutal without needing extra gloss.
