(CNN) — Two girls accused of stabbing a friend to impress the fictional Internet bogeyman Slenderman have been found competent to stand trial.
The decision came out of a Wisconsin courtroom Thursday, Waukesha County Circuit Court reporter Kathy Fus told CNN.
According to a criminal complaint, the suspects were arrested hours after the victim was discovered.
The girls were allegedly trying to please Slenderman, a horror story meme the girls had encountered on a website known as Creepypasta Wiki.
One of the suspects is said to have told police that Slenderman is the site’s supposed leader, and to climb into his realm, a user must kill someone.
Geyser and Weier are being charged as adults. A preliminary hearing is set for February 18.
