Who is Morgan Geyser? All on convict's psychotic spectrum disorder

Geyser, now aged 23, was placed in a group home to continue her treatment for a psychotic spectrum disorder. Alongside her co-defendant Anissa Weier, she faced charges of attempted homicide stemming from the 2014 stabbing incident involving their friend, Payton Leutner.

At the age of 12, both Geyser and Weier in 2014 enticed Leutner into a wooded area in Waukesha, located near Milwaukee, where they stabbed her 19 times.

The girls claimed that the stabbing was carried out to satisfy the demands of the fictional character Slender Man. In 2017, both were found not guilty by reason of mental defect or disease and were subsequently sentenced to mental confinement.

Weier was sentenced to 25 years but was granted conditional release in 2021 under a 25-year commitment order. She was released from electronic monitoring in 2023.

In contrast, Geyser received a sentence of 40 years of mental confinement.
