Morgan Geyser, one of the two convicted individuals in the infamous 2014 “Slender Man” stabbing case, briefly went missing in late 2025 after being released from a mental institution and brought to a group home. The case attracted attention across the country, as all suspects and the victim were 12 years old at the time that Geyser and a friend stabbed their classmate to prove that “Slender Man” — the fictional supernatural internet meme — was real.
Below, learn about the “Slender Man” stabbing case and who Geyser is.
Who Is Morgan Geyser?
Geyser is a Wisconsin native who was convicted of stabbing classmate Payton Leutner when both were 12 years old. Geyser and friend Anissa Weier lured Leutner to a park in 2014 and stabbed Leutner multiple times in order to prove that Slender Man existed. Miraculously, Leutner survived.
In 2017, Weier and Geyser were found not guilty by mental disease or defect, and they were committed to mental institutions. Geyser was sentenced to 40 years to life, while Weier was sentenced to 25 years to life. Both were released early; Weier went to live with her family in 2021, and Geyser was released in early 2025 to live in a group home.
