The victim was eventually found and hospitalized, and the accused classmates were soon arrested, where it was revealed that the girls had committed the violent act because they thought it would impress Slenderman, who is known in the lore for bringing harm to children.
And who is also the subject of some video games, indie flicks and an upcoming Sony feature.
Beware the Slenderman, aside from introducing the ghastly entity to unsuspecting audiences, will focus on the real-life Wisconsin crimes and trial of two then-preteen females who, in 2014, allegedly coaxed a fellow female classmate out into the woods and left her for dead after stabbing her 19 times.
