Disturbing Video Shows Teen Admit To 'Slenderman' Stabbing Attack: 'We Were Trying To Kill Her'

 "I might as well just say it. We were trying to kill her."

The Slenderman Case, Explained

Anissa Weier and Morgan Geyser became the subjects of international fascination after the two 12-year-olds repeatedly stabbed a classmate and left her for dead. The attempted killing was motivated by a mysterious internet ghoul named Slenderman — a digital urban legend who haunted the dreams of the criminal children.

Their victim survived the heinous attack, and both children were charged in the stabbing. Weier was sentenced to 25 years in a state mental hospital in December, and Geyser will receive her sentence later today.

A disturbing video of Geyser being interrogated by police shortly after the stabbing has also been released today. In the footage, Geyser admits that the goal was to kill their victim in the name of the spooky, otherworldly presence known as Slenderman, in the hopes of protecting their families from his spectral wrath.

The attack occurred on May 31, 2014. Geyser and Weier lured a classmate to a park in Waukesha, Wisconsin, and stabbed her 19 times. The bleeding child was discovered on the side of the road by passersby.

The video shows Geyser only a few hours after the attack. 

"What were you trying to do with her when you stabbed her?" asks a detective.

"Kill her," Geyser responds. "I might as well just say it. We were trying to kill her."

Later, in interviews, Geyser's mother would remark that she was shocked by her daughter's lack of remorse when discussing the attempted killing.

"The interrogation is very difficult to watch because that’s not my daughter saying those things," Angie Geyser told ABC News. "That’s not the way that she speaks, that’s not the way that she acts [...] [Morgan] appears to have no remorse for what’s happened and she just talks about it in such a flat manner.”

Geyser pleaded guilty to the crime by reason of mental illness. Based on psychiatric evaluations, a judge will determine how long she will be confined to a state psychiatric today, reported the Chicago Tribune.

“Though we do not believe that an institution is where these attempted murderers belong, the current legal system does not favor victims in this situation," the victim's family has since communicated in a statement.

ABC will run a special on Friday's episode of "20/20" that discusses the complexities of the infamous Slenderman situation.

Meanwhile, a horror movie about Slenderman has provoked condemnation from the Weier family.

"It's absurd they want to make a movie like this," Bill Weier said. "It's popularizing a tragedy is what it's doing. I'm not surprised, but in my opinion it's extremely distasteful. All we're doing is extending the pain all three of these families have gone through."
