HBO Explores Origins of Slenderman & 2014 Stabbing

HBO explores the mythos of the digital-age bogeyman known as Slenderman in a new documentary, titled Beware the Slenderman.

The fictional character is a faceless, unnaturally tall man who stalks children or young people and persuades them to do ghastly things. Its influence was ultimately felt in the real world back in 2014, when two 12-year-old girls lured their friend into the woods for a brutal murder.

While uncovering the Slenderman's origins, the documentary focuses on the 2014 attempted murder, which the two girls carried out in an attempt to appease Slenderman.

Beware the Slenderman debuted earlier this year at SXSW, and will air on HBO soon.
