Two Wisconsin girls accused in the "Slender Man" stabbing case entered not guilty pleas.
ABC News reports Judge Michael O. Bohren confirmed in court Friday that the two 13-year-old girls will be tried together as adults.
Their trial date has been set for Oct. 15, with both girls facing first-degree attempted homicide charges.
The two girls, who were 12 at the time, are accused of luring their 12-year-old school friend into the woods in Waukesha, before stabbing her 19 times in spring of 2014.
At the time, they told the investigators that the attack – which the girl survived – was carried out to please "Slender Man," a fantasy horror character that they believed to be real.
According to the Washington Post, they believed the tall, faceless "Slender Man" would reward them by letting them live in his mansion, which they though was in Nicolet National Forest in Wisconsin – 300 miles from their home.
If the pair are convicted as adults, they would stay in a juvenile facility until they're 18, then serve out the rest of their sentence in an adult prison, the newspaper notes. The charge of attempted first-degree intentional homicide carries a maximum 45-year sentence.
