POSEN, Ill. (WGN) – Recently acquired body camera footage from Nexstar’s WGN captures the dramatic moment officers discovered a Wisconsin woman who had disappeared from her group home. This woman, previously convicted in the notorious 2014 “Slender Man” stabbing case, was on the loose for more than a day.

Morgan Geyser, now 23 years old, faces an extradition hearing scheduled for Tuesday after authorities found her in Posen, Illinois, a location over 150 miles away from her Wisconsin group home.

Back in 2014, Geyser, alongside another girl, admitted to the charge of first-degree attempted intentional homicide for stabbing their classmate, Payton Leutner, 19 times. At that time, all three were just 12 years old, and the attack occurred after a sleepover, in a secluded wooded area in Waukesha, Wisconsin.

Despite being left critically injured in the woods, Leutner managed to survive the brutal assault, finding her way to a nearby bike path where she was eventually rescued by a passerby.

During police interrogations, Geyser and her accomplice confessed that they committed the stabbing to satisfy the demands of “Slender Man,” a fictional, sinister figure from the internet, whom they believed would harm their families if they did not comply.

Both pleas were later vacated when they were found not guilty by reason of mental disease or defect.

Geyser was initially ordered committed to a psychiatric hospital for 40 years. A Waukesha County Circuit Court judge sent her to the Winnebago Mental Health Institute. Geyser, records show, petitioned four times for her release.

Despite strong opposition from prosecutors, a judge signed off on her fourth petition last January, allowing for conditional release. State Department of Health officials made a last-minute attempt to keep her committed, but a judge rejected that request.

In September, she was transferred to a group home in Madison, Wisconsin, a move the Waukesha County District Attorney was against.

“We support that she should have been in custody. Not only should she have been in custody since 2014 forward, but also the attorney and I argued vehemently for her not to be released to conditional release,” Lesli S. Boese said during a press conference Monday.

After she escaped the group home, Madison police on Sunday issued an alert saying Geyser was last seen around 8 p.m. the previous day with an adult acquaintance.

Authorities with the Wisconsin Department of Corrections also said their records showed a malfunction alert from Geyser’s bracelet on Saturday night, but that Geyser’s escape wasn’t reported to Madison police until Sunday morning when the group home called 911.

Boese, the Waukesha County District Attorney, said Leutner’s family was never notified of Geyser’s escape prior to a call from her office. She said there was a serious concern for their safety as Geyser remained on the run.

“We found out (Sunday) morning about Morgan’s escape. The victim-witness was immediately notified of this information,” Boese said. “We were told that they had not been informed, prior to us reaching out to them, that Morgan had escaped.”

Geyser and the adult acquaintance were spotted around 9 p.m. Sunday in Posen by a gas station clerk who called police to report two people loitering. The clerk, who appeared in video from officers’ body-worn cameras, told police she was concerned about the pair being outside in the cold.

“The officers arrived and found them sleeping on the ground with a bunch of bags around them containing clothing and things like that, like they were traveling,” Posen Police Chief William Alexander said. “The officers woke them up and asked for identification and who they were.”

In the body-worn footage, an officer can be heard saying, “Hey, you guys. I just want to make sure you guys are OK.”

“Initially, they were reluctant to give any type of identification, and then they gave them two names, but the names that they gave them came back with nothing, no information,” Alexander said.

Alexander said the reluctance raised red flags for the responding officers, who asked the pair if they were missing and said they wanted to figure out who they were, so they could have them on their way if they hadn’t done anything wrong.

“Give me your name and date of birth. You’re not wanted for murder, right?” an officer asks in the footage.

“Right,” Geyser responds.

“OK, then there shouldn’t be any problem,” another officer says.

Nearly nine minutes after officers arrived, Geyser can be heard giving officers her real name. According to Alexander, she suggested officers could “just Google” her, because she had done something bad, and they would know who she was.

“That’s my name. Trust me, I didn’t want to give it to you, you’ll see why in a second,” Geyser told officers.

Body-camera video shows Geyser was adamant that the person with her was innocent.

“I did something wrong, she didn’t. She doesn’t know what I did,” Geyser told the officer, referring to her friend, who had run off with her.

“What did you do wrong?” an officer asked in response.

Geyser was taken into custody along with 43-year-old Charly, a transgender woman whose government name, according to arrest documents, is Chad Mecca.

Charly, who is charged with criminal trespassing and obstructing identification, spoke exclusively with WGN’s Sean Lewis and said Geyser suggested leaving Wisconsin.

“We didn’t really have a plan. Just to get as far away as we could. Just vanish,” Charly said.

An arrest report shows Geyser told officers the two met a few months ago at church. She claimed she was treated unfairly at the group home and was upset she could no longer see Charly, who had previously snuck inside the home by climbing through a window.

“They were going to take me away. I’m the only friend she has, and they were trying to railroad me so I couldn’t go there anymore,” Charly told WGN. “She’s my best friend. She’s my only real friend.”

Geyser told police, according to the arrest report, that she cut off her electronic monitoring bracelet with scissors and was going to potentially head to Nashville, Tennessee. She said the pair took a Greyhound bus from Wisconsin.

“I was very happy that the clerk had called us, and I am proud of my officers for pushing to establish their correct identity and take them off the street, because that is somebody we do not want in our town or communities at all,” Alexander said. “You never know what you’re going to run into as a law enforcement officer. It could be the simplest of calls, and there you have it, now it’s national news.”

Video from inside a squad car on Monday showed Geyser being transported to the courthouse in Markham. At one point, she began to sob after the officer driving exits the vehicle.

“I’m sorry, God. I’m sorry,” Geyser could be heard saying. “I’m so sorry. I wish I hadn’t.”

Geyser is being held in jail in Cook County as she awaits extradition back to Wisconsin.

Boese told reporters her office does not have jurisdiction in Geyser’s case due to the group home being located in a different county. She said any charging decisions would be made by the Dane County District Attorney’s Office.

Once Geyser is back in Wisconsin, it will be DHS that will decide whether to file a petition to revoke the 23-year-old’s conditional release. Boese said her office fully supports that.

“Our office will not get involved again in this case until a motion to revoke conditional release is filed,” Boese said.
