‘Slender Man’ stabber cuts off ankle monitor and escapes

A woman who viciously stabbed her classmate 19 times when she was just 12-years-old has escaped custody, sparking a manhunt.

One of the “Slender Man stabbers,” who viciously ambushed and hacked a classmate almost to death when she was 12 years old, has gone missing.

Morgan Geyser, 23, cut off her ankle monitor and escaped from her group home where she is living.

US authorities have now launched a search, as she remains on the run, the New York Post reports.

“Her whereabouts are unknown as of Sunday morning,” police said.

Geyser was placed in the facility this year after being granted conditional release from the Winnebago Mental Health Institute.

She was sent to the psychiatric unit in 2018 after pleading guilty to attempted first-degree intentional homicide as part of a deal with prosecutors to avoid prison.

In 2014, Geyser, along with her friend Anissa Weier, lured fellow classmate, Payton Leutner, into a wooded area of a Wisconsin park.

The group had been playing hide and seek during a sleepover, before Geyser brutally stabbed the girl 19 times.

Weier cheered on the frenzy as it unfolded.

All three of the girls were 12-years-old at the time.

The attack was an effort to impress “Slender Man,” a fictional character created in 2009 on the Something Awful internet forum.

The illustration of the tall, thin man with long arms and magical abilities circulated the internet, becoming a viral ghost story for young people. It later went onto become the subject of a 2018 horror movie.

The girls believed the imaginative character had been real.

Miraculously, the young victim survived the horrifying assault, crawling her way to safety until she was found by a passing by cyclist.

Both Geyser and Weier were charged with attempted murder charges and faced trial as adults, despite their ages.

In 2018, Geyser plead guilty in a deal that would see her put in a mental institution instead of serving jail time.

She has spent nearly seven years in the Winnebago Mental Health Institute with her release ordered back in January.

Weier was released in 2021 after four years at the same institute.

She had been approved for transfer to a group home, however the facility withdrew its offer following backlash.

However police confirmed to WMTV that Geyser was staying at a group home in Madison. She was last seen around 8pm. Saturday with an adult acquaintance, according to officers.
