Beware the Slenderman (2016x1)

Air date: Mar 11, 2016

The mythos of a faceless, digital-age bogeyman known as Slenderman was created on the Internet, but his influence was felt in the real world when two 12-year-old girls lured their friend into the woods for a brutal murder. Beware the Slenderman tells the true story of 12-year olds Morgan Geyser and Anissa Weier, who lured their best friend into the woods, stabbed her 19 times, then confessed they did it to appease a tall and faceless man known online as Slenderman.
