Back in 2014 on May 31th, two twelve-year-old girls attempted to kill their peer by repeatedly stabbing her after luring her into a wooded park during a sleepover. Payton Leutner(12) was stabbed a total of 19 times and miraculously survived. She crawled to a nearby street and received help from a man biking past. He saw the poor girl covered in blood and immediately called for help.

Anissa Weier and Morgan Geyser believed that if they attacked Payton they would gain favor from a fictional creature called Slender Man in hopes of getting to enter the Slender Man Mansion.

Both girls were found not guilty by reason of mental disease or defect and were sentenced to decades of institutional confinement. However, Anissa Weier was released after less than four years in 2021.

A brief history of Anissa Weier

Very little is known about the childhood and upbringing of Weier. We know that she was born on November 10th, 2021 and her parents are Bill and Kristi Weier. Regardless of whatever transpired in her childhood, I am confident the parents never could’ve imagined what their daughter was capable of.

Based on one article from ABC News, it appears that Weier had met Geyser and Leutner in school and became friends quickly. Leutner had sought out Geyser to befriend her after witnessing Geyser sit alone at lunch most days. However, Weier and Leutner were newer friends when the attack occurred.

After Weier and Geyser were found shortly after the stabbing in a furniture store almost 5 miles from the incident.

In 2017, Weier plead guilty to attempted second-degree homicide but was found not guilty due to mental disease or defect. She was sentenced to 25 years to life for the crime, three of which would be served in psychiatric institution. The remaining 37 years were to be completed under supervision.

3 years in a state institution

Weier wrote a letter to Judge Michael Bohren just before her court hearing in March, 2021. The latter stated the following”

“I am sorry and deeply regretful…
