Morgan Geyser: 5 Fast Facts You Need to Know

Two Wisconsin tweens lured their friend to an overnight birthday party then stabbed her 19 times and left her for dead in the woods as a sacrifice to a mythical Internet character, cops said.

Morgan Geyser and Anissa Weir are charged as adults with first-degree intentional homicide and face up to 65 years in prison if convicted. They were arraigned on the charges Monday as more disturbing details about the case emerged.

Cops say the stabbing came about because of the girls’ obsession with Slender Man, a character created as an Internet meme.

To show their loyalty to Slender Man and to prove the creature was real, they planned to kill their friend and very nearly succeeded in doing so. The victim sustained 19 stab wounds, one of which was a millimeter away from hitting an artery that would have left her dead within minutes. Geyser’s attorney is seeking she undergo a mental evaluation as quickly as possible, according to the Milwaukee Journal Sentinel.

1. The Suspects Wanted to Kill Someone to Become ‘Proxies’ of Slender Man

The suspects told cops they wanted to kill the victim as a sacrifice to Slender Man, whom they thought they’d meet after committing the slaying, enabling them to prove to skeptics that the mythical creature was real.

Geyser and Weier thought that Slender lived in a mansion inside Nicolet National Forest in northern Wisconsin, and the two planned to make the 318-mile walk to the forest after killing their friend.

They explained to cops that killing another person would qualify them as “proxies” to Slender Man, putting them two steps below the character in Slender’s pecking order.

According to the criminal complaint, Weier told cops that she and Geyser had been inspired by the Creepypasta website, where users exchange horror stories and stories about nightmares. That’s where the duo learned about Slender Man, who was apparently developed on the web forum Something Awful by a user named Eric Knudsen (a.k.a “Victor Surge”).

Geyser told police she and Weier had to kill their friend because, if they didn’t, Slender Man would kill their families. She said “it seemed necessary” because Slender Man can read minds and teleport. She also told cops she sees Slender Man in her dreams and she’s prone to “Slender sickness” because of “Slender radiation.”

2. The Victim Was ‘1 Millimeter Away From Certain Death’

Doctors at Waukesha Memorial Hospital told police that one of the victim’s stab wounds came within a millimeter of hitting an artery near her heart. Had the artery been punctured, the victim faced “certain death” and likely would have died within minutes of the attack.

The victim, identified in the criminal complaint as P.L., miraculously managed to stumble out of the woods, where she was discovered by a bicyclist. She’s fighting for her life, but listed in stable condition after undergoing surgery.

3. Geyser Felt No Remorse for What She Did

Morgan Geyser is one of two tween suspects in the horrific stabbing of a 12-year-old girl in Wisconsin, an apparent sacrifice to the mythical Slender Man.

The criminal complaint says Geyser was the mastermind of the attack and started plotting it in February, when she set a date for her birthday celebration. The complaint says Geyser and Weier would talk on the school bus about their plan, using code words so they wouldn’t get caught.

Geyser and Weier initially discussed killing their friend inside Geyser’s house, but later decided they would go into the woods and lure the victim into a game of hide-and-seek before stabbing her. After the two carried out the attack, the victim got up to try to walk out of the woods for help, but Weier directed the victim away from the street and told her to lie down.

The complaint says after Geyser admitted to the attack, she said she felt no regret after carrying it out:

Geyser stated they ran up the road and they saw a police officer had come to the scene and they were hiding in the woods. At one point Geyser stated she was sorry. When asked what happened to the knife after they stabbed P.L., Geyser stated Geyser put the knife back into her bag and wiped it off on her jacket. Geyser than stated to Detective Casey, “it was weird that I didn’t feel remorse.”

Geyser and Weier were questioned without legal council present, according to the Milwaukee Journal Sentinel. Geyser’s attorney, Anthony Cotton, said it’s too early to tell if any of the girls’ statements will be struck down in court.

On August 1, Waukesha County Judge Michael Bohren ruled that Morgan Geyser was not mentally competent enough to stand trial, USA Today reports. According to ABC News, Weier has not gone under any psychiatric evaluations.

4. Weier Told Geyser ‘Go Ballistic, Go Crazy’ Before Geyser Attacked the Victim

According to the criminal complaint, Weier, seen in the Vine above rolling her eyes into the back of her head, told detectives that Geyser almost couldn’t stab the victim as planned because she had a nervous breakdown. The complaint reads:

Weier indicated they eventually ended up in the bathroom where Weier was going to do the stabbing because Weier knew all the weak spots. Once in the bathroom, Geyser handed Weier the knife and Weier explained that Geyser grabbed a hold of P.L.’s arms in a stall almost restraining her. Weier stated she needed to talk to Geyser and told Geyser she couldn’t do it. Weier gave the knife back to Geyser at which time Weier indicted Geyser attempted to restrain P.L. but Geyser had a nervous breakdown and Weier had to calm Geyser down.

The report continues:

Geyser then gave Weier the knife and Weier told Geyser that Weier was too squeamish and gave the knife back to Geyser. Weier indicated she and Geyser were doing this all secretly so P.L. would never know. Weier stated once Geyser got the knife back Geyser told Weier, “I’m not going to until you tell me to.” Weier stated she started walking away from Geyser and told Geyser, “go ballistic, go crazy.” Geyser said that Geyser would go ballistic and Weier said now.
