What was the Slenderman stabbing case and what is happening with Morgan Geyser now?

The Slenderman case involved Morgan Geyser who, at age 12, along with friends, stabbed a classmate 19 times to impress a fictional online character called Slenderman. The victim barely survived this shocking attack perpetrated by her own friends. Now 22 years old, Morgan Geyser recently appeared in a Wisconsin courtroom where she was granted a chance for release from a mental health facility. After spending nearly a decade institutionalized, her case raises important questions about juvenile crime, mental health treatment, and rehabilitation.
