On this Tooth & Nail True Crime episode hosts Mindy and Lukas dig into two chilling, unsolved Missouri cases: the "Missouri River Killer" (aka the Avenue Mutilator), linked to multiple dismembered victims found along the Missouri River between 1982 and 1994, and the 1992 disappearance of the Springfield Three—Susie Streeter, Stacey McCall, and Cheryl Levitt—who vanished from a home with no clear trace.

The hosts review the facts, suspects, investigation missteps, and lingering questions behind both cases, all delivered with the show’s blunt banter and sharp curiosity.
