In this episode of "The Spark That Lit the Flame," we examine the haunting case of the Slender Man stabbing. In 2014, two 12-year-old girls in Waukesha, Wisconsin, lured their friend into the woods and stabbed her 19 times—claiming they acted at the behest of the fictional internet character, Slender Man. Through a blend of case details, psychological analysis, and cultural context, we explore how online myths, shared delusions, and adolescent vulnerability combined to spark a crime that shocked the world. Join us as we uncover the disturbing reality behind the legend, and reflect on what this case reveals about belief, mental health, and the digital age.
