HBO is set to air a documentary about Slenderman, a fictional character with supernatural abilities created by Erick Knudsen in 2009.
The character is described as unnaturally tall with long legs and tentacle-like arms. He has a white featureless face and is usually shown wearing a dark suit with a tie.
Slenderman became infamous in May 2014 when two 12-year-old girls, Morgan Geyser and Anissa Weier, lured a classmate into the woods during a sleepover and stabbed her 19 times.
The victim, Payton Leutner, dragged herself out of the woods and was found by a bicyclist who called 911. Leutner was taken into surgery and survived.
Geyser and Weier claimed to have stabbed Leutner as a sacrifice to Slenderman.
The girls said they were convinced the fictional character was real and that he would kill their families if they didn’t win his approval by sacrificing someone.
According to an Associated Press article published on Sept. 30, 2015, Judge Michael Bohren stayed the case until an appeals court could determine if the girls should be tried in juvenile or adult court.
The initial decision was scheduled for January 2016, but has been pushed to April because of an extension requested by an attorney of one of the accused girls.

The HBO documentary will focus on the crime and the impressionability of consumers as it relates to media.
“Beware the Slenderman” premiers March 11 at the South by Southwest film festival in Austin, Texas. The documentary airdate for HBO has yet to be announced.
