Luna Andrews

Luna Marie Andrews, 16, stabbed and cut the throat of Kai Chong, 14, and kept her body in her bedroom. She was suffering from schizophrenia and autism spectrum disorder. She wrote a note.

''My name is Luna. I am the actress starring in your bad dreams, Kai. I murdered someone in preschool when I was 2. I murdered the teacher, Mrs. Katz. She was 40. I was an expelled student in Royal High, but I came back. I am extremely depressed and I need therapy. I am a convicted child murderer. Chloe is now going to be sad all the time because she misses her sister so much. I don't care. Normal is boring. I am in prison, and that's what matters now. I was very jealous. I hated Kai. Bye-Bye!''

Luna was sentenced to death.
