Wisconsin authorities are on high alert after Morgan Geyser, 23, one of the attackers involved in the infamous 2014 Slender Man stabbing, escaped her group home in Sun Prairie on Saturday night by removing her ankle monitor. Law enforcement issued an official alert on Sunday, urging anyone who spots Geyser to call 911 immediately. Her attorney, Tony Cotton, advised her to surrender voluntarily, stressing that it is in her best interest.

Geyser first gained notoriety over a decade ago, when at the age of 12, she and friend Anissa Weier lured classmate Peyton Leutner into the woods of Waukesha during a sleepover. Geyser stabbed Leutner 19 times while Weier encouraged the assault. The girls reportedly believed that by harming Leutner, they would become proxies of the fictional character Slender Man, an online creation by Eric Knudsen in 2009. Leutner miraculously survived, crawling out of the woods to be discovered by a cyclist.

Both girls were charged in adult court with first-degree attempted intentional homicide. Weier pleaded guilty to a lesser charge but was found not guilty by reason of mental disease or defect in 2017, ultimately serving time in a mental hospital before her release in 2021.

Geyser, diagnosed with schizophrenia, pleaded guilty to first-degree murder but was also found not guilty by reason of mental disease or defect in 2018. She was initially committed to a psychiatric hospital for 40 years, though she served only about 25 percent of her sentence. Earlier this year, Waukesha County Circuit Judge Michael Bohren conditionally released Geyser to a group home for continued treatment, following testimony from mental health experts.

Drs. Brooke Lundbohm and Kenneth Robbins concluded that Geyser had made progress and no longer exhibited persistent psychosis that contributed to the assault. Robbins suggested her previous symptoms might have stemmed from trauma, including claims of sexual abuse by her father, who died in 2023, and might now align more closely with PTSD, anxiety, and autism.

During the January hearing, Geyser also came out as transgender, though court proceedings maintained female pronouns for consistency. Her transition from secure psychiatric care to a group home faced multiple obstacles, including refusals from other homes and pushback from state health officials concerned about her readiness. Authorities had raised alarms after evidence surfaced of troubling correspondence with an older man named Jeffrey, known for selling murder memorabilia. While Geyser reportedly destroyed the letter and requested a no-contact order, previous communications raised safety concerns.

As of now, law enforcement continues to search for Geyser, cautioning the public to remain vigilant and report any sightings. The escape reignites attention on the 2014 case and underscores the ongoing challenges of balancing mental health treatment with public safety in high-profile criminal cases.
