Prosecutors want 15-year-old Morgan Geyser to spend the maximum 40 years in a mental hospital for stabbing a classmate in suburban Milwaukee in 2014. But Geyser’s attorneys will make their own case for what they believe is best for Geyser. The hearing will include victim impact statements and doctors who have evaluated Geyser. She pleaded guilty to attempted first-degree intentional homicide in October in a deal with prosecutors to avoid prison. Geyser and Anissa Weier lured the classmate into the woods in a park and repeatedly stabbed her with a kitchen knife. Geyser stabbed the classmate 19 times while Weier urged her on, according to investigators. The classmate was left for dead but she crawled out of the woods and got help from a passing bicyclist. She and her attackers were all 12 at the time. Weier was sentenced to 25 years in a mental hospital in December. Geyser’s attorneys have argued in court documents that she suffers from schizophrenia and psychotic spectrum disorder, making her prone to delusions and paranoid beliefs. A psychiatrist hired by her attorneys previously testified that Geyser believed she could communicate telepathically with Slender Man and could see and hear other fictional characters.
