 According to her account , Lhermitte then told daughter Myriam that she had a surprise for her in the office . When Myriam entered the office , Lhermitte told her to sit on a chair and wear a blue handkerchief over her eyes . Once Myriam was seated , Lhermitte took a marble plaque she found nearby and smashed it over Myriam 's head , and then cut her throat . Nora , who was allegedly Dr. Schaar 's favorite goddaughter , was asked to sit in a chair while Lhermitte slit her throat from behind . After Nora had been killed , Lhermitte wrote the letters " <unk> " on the bathroom mirror in Nora 's blood , and later stated that she had intended to spell the name " Judas . "
