A woman from Wisconsin disappeared from her group home on Saturday after removing a monitoring bracelet issued by the Department of Corrections. She was located in Illinois the following day, alongside a 42-year-old man, according to law enforcement.

Morgan Geyser, 23, was detained with the unidentified man, believed to be her companion, at a Thornton truck stop in Posen, Illinois. Local police reported that they had traveled there by bus.

Geyser went missing on Saturday after she was last spotted in Madison, Wisconsin, with an adult companion. There was an unexplained delay of 12 hours between her disappearance and when authorities were informed.

The Department of Corrections reached out to the group home a couple of hours after Geyser’s ankle monitor showed signs of tampering. It was through this communication that the group home realized she was gone.

Madison police were only informed about Geyser’s disappearance on Sunday morning when the group home contacted them.

Earlier this fall, Geyser was relocated to a group home for treatment related to a psychotic spectrum disorder, though the specifics of the facility’s location remain confidential by court order.

According to CBS, Geyser and the man were found sleeping on the sidewalk after Posen police were called about two people loitering behind a building. Geyser allegedly gave officers a false name before saying she did not want to disclose her identity because she had “done something really bad.”

At some point, Geyser reportedly suggested officers could “just Google” her.

Geyser was 12 in 2014 when she and Anissa Weier nearly stabbed a female classmate to death. After a sleepover celebrating Geyser’s 12th birthday, she and Weier lured the classmate to the woods  — where they stabbed her 19 times and left her for dead.

The girls claimed they carried out the attack to appease “Slender Man,” an internet meme. They also said they believed their families would be harmed if they did not attack their classmate, who survived.

Geyser and Weier were found not guilty due to mental disease or defect. Weier was released from a mental institution in 2021. Geyser remained institutionalized despite seeking her release on four occasions.

However, in March, a judge granted Geyer’s petition for conditional release. In July, a Sun Prairie group home rescinded its offer to take in Geyser as a resident. Geyser’s attorney said it was due to negative publicity.

According to reports, the man Geyser was found with was charged with criminal trespassing and obstructing identification, as he also lied about his identity. He has since been released from custody.

Geyser, who remains in custody, will be transferred to Cook County jail for an extradition hearing.
