Those I cared about the most,” Anissa Weier, 15, said in court on Monday, according to the Associated Press. Weier and the other suspect, Morgan Geyser, [were both 12](http://time.com/4649890/beware-the-slenderman/ "undefined") in 2014, when they are accused of attacking Payton Leutner in a park in Waukesha, Wisc., after a sleepover. Leutner, who was also 12 at the time, survived the attack. Geyser has pleaded not guilty by reason of mental disease, the AP reported. Weier will face a trial next month that will determine whether she is not guilty because of mental illness. Based on the finding, Weier could face three years in a mental hospital or up to 10 years in prison. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4910238/wisconsin-slender-man-attack-guilty-plea-anissa-weier/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4910238/wisconsin-slender-man-attack-guilty-plea-anissa-weier/"},"headline":"Wisconsin Teen Pleads Guilty in Stabbing Attack Inspired by 'Slender Man'","datePublished":"2017-08-22T00:47:06.000Z","dateModified":"2026-02-23T17:06:25.720Z","description":"She and another teen are accused of stabbing a classmate 19 times","url":"https://time.com/4910238/wisconsin-slender-man-attack-guilty-plea-anissa-weier/","keywords":["Wisconsin","Crime","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdf9de1c26069b468/6988da8ebc6cfc5e5c3e2bb0/slenderman-plea-wisconsin.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Katie Reilly","jobTitle":null,"url":"https://time.com/author/katie-reilly/"}],"articleSection":"U.S.","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdf9de1c26069b468/6988da8ebc6cfc5e5c3e2bb0/slenderman-plea-wisconsin.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Girls Stabbing Plot","caption":"Girls Stabbing Plot","creditText":"Michael Sears—Milwaukee Journal-Sentinel/AP","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/us/","name":"U.S."}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/wisconsin/","name":"Wisconsin"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4910238/wisconsin-slender-man-attack-guilty-plea-anissa-weier/","name":"Wisconsin Teen Pleads Guilty in Stabbing Attack Inspired by 'Slender Man'"}}]}] ```
