Madison police released this image of Morgan Geyser, which was captured on security video in November 2025. The department was notified of her disappearance from a group home on Sunday morning, Nov. 23, and immediately alerted the public.

Madison, Wisconsin authorities say Morgan Geyser, who was granted conditional release earlier this year in the Slender Man case, is missing after she cut off her Department of Corrections monitoring bracelet and left a group home.

Geyser was last seen in the area of Kroncke Drive around 8 p.m. on Nov. 22 with an adult acquaintance, according to the Madison Police Department. Her whereabouts are unknown, and anyone who sees Geyser is asked to call 911.

Madison police said they were notified of her disappearance Sunday morning, Nov. 23, and immediately alerted the public.

An MPD representative, reached by phone, said the department was alerted just before 8 a.m. The department posted on their website about 45 minutes later, and on Facebook at around 10 a.m.

About 12 hours passed between the time Geyser was last seen and the moment the public was notified.

Other agencies are assisting in search for Morgan Geyser

The state Department of Corrections' Electronic Monitoring Center gets notified when a device is tampered with, according to the DOC's website. The DOC did not immediately respond to a phone call and email seeking more information about the notification process.

On Nov. 19, a few days before Geyser's disappearance, a Madison woman removed her GPS bracelet and went missing. In that case, Dane County Sheriff's deputies monitoring the jail diversion program received an alert from her GPS bracelet.

Suburban Madison police agencies are assisting with the search for Geyser, the MPD representative said. Police did not confirm the name of Geyser's group home for safety reasons.

The Dane County Sheriff's Office is not involved in the search, the sheriff's office told the Milwaukee Journal Sentinel, part of the USA TODAY Network.

Reached by phone Sunday morning, Nov. 23, Geyser's attorney, Tony Cotton, said he had no information and police had not yet contacted him.

Morgan Geyser was placed in group home, location sealed

Earlier this fall, Geyser was placed in a group home where she would continue treatment for a psychotic spectrum disorder, but the exact location was sealed by the court.

Geyser's placement brought an end to a 2025 saga that began with her finally gaining court approval for conditional release in January, only to have the process face setbacks and challenges throughout the year.

In July, a group home in Sun Prairie, a suburb of Madison, withdrew its offer to accept Geyser as a resident. Two other group homes, one in Manitowoc and the other in the Milwaukee area, also fell through, for different reasons.

'Slender Man' case dates to 2014

Geyser, now 23, along with co-defendant Anissa Weier, were charged with attempted homicide of their friend, Payton Leutner, who was stabbed 19 times near David's Park in Waukesha in May 2014. All three girls were 12 years old at the time.

Believing that they were doing the bidding of the fictional online character called Slender Man, both were found not guilty by reason of mental defect or disease in 2017 and sentenced to mental confinement — Weier for 25 years, and Geyser for 40 years.

Weier was granted conditional release in 2021 on a 25-year commitment order. She was freed from electronic monitoring in 2023, according to court records.
