Authorities say two 12-year-old girls stabbed their friend, another 12-year-old girl, in Wisconsin on June 1 after planning the crime for months. According to the Huffington Post, Waukesha Police Chief Russell Jack said the suspects, identified as Anissa Weier and Morgan Geyser, invited the victim to a sleepover at one of their homes on Friday May 30. Jack added that as the girls played in a wooded area early Saturday morning, one held the victim down while the other stabbed her 19 times in the "arms, legs, and torso."

CNN reports that the aggressors had been plotting the brutal attack since February:

They first thought to kill the victim by placing duct tape over her mouth while she was sleeping and stabbing her in the neck, the complaint read.

Next, the plan was to kill her in a bathroom where there was floor drain that could make cleanup easier, it continued.

But, finally, the girls decided to do it in a park while playing a game of hide-and-seek, the complaint read.

Furthermore, CNN adds that Jack explained the motive to reporters during a press conference: "Both suspects had a fascination with a fictitious character [that's] often posted "to websites dealing with stories about death and horror," he said. According to the New York Daily News, one of the suspects told police that the attempted murder was an offering to a demonic figure named Slender Man:

According to a criminal complaint, one of the two girls told a detective they were trying to become "proxies" of a mythological demon-like character called Slender Man, which they learned about on, a website about horror stories and legends.

Though she suffered serious wounds to "several" major organs, the victim was still able to crawl out of the woods, where a bicyclist spotted her and called 911.

Geyser and Weiler have been charged as adults with first-degree intentional homicide. As of yesterday, the victim was in stable condition at Waukesha Memorial Hospital.
