It's 4:18am on April 18, 2016. 45-year-old fitness instructor and mother of three, Missy Bevers, arrives at the Creekside Church in Midlothian, TX to host a boot-camp style workout that's being held indoors due to heavy rain. Upon entering the building alone, however, Missy is attacked by a vicious assailant, and soon after found unresponsive when her students begin to arrive. In the aftermath, investigators make a harrowing discovery on the church's motion-activated surveillance footage: a person in full police tactical gear carrying a hammer the cops say matches Missy's wounds. Three years later, however, we still don't know the killer's identity, and the investigation is no closer to bringing closure to the family than when it started. Join host Ryan Kraus for a psychological examination of the crime, in an effort to uncover the motive and profile of a killer, and finally answer one burning question: Who killed Missy Bevers?
