Sonya Caleffi, a 34-year-old nurse at Manzoni Hospital of Lecco, Italy, near Lake Como, was arrested December 15, 2004 and made a written confession to six killings. Caleffi was anorexic and had in the past attempted suicide on three occasions between 2002 and 2004. Following her arrest police discovered in her home large number of books about mental illness (bulimia, anorexia nervosa) and death. The nurse kept a diary noting details of her patient’s deaths, 22 of who who had died on her shift.
In her confession Caleffi stated: "I just wanted to attract attention because I felt undervalued. And then those people had only a short time to live made me feel pity. That's why I picked up the pace of their death." She later retracted the confession. She gave a television interview to Panorama saying she remembered only the final patient to died under her care, Maria Cristina, a 99-year-old woman admitted to the hospital for routine care. She said that she had fabricated most of the earlier confession. Caleffi claimed in her TV interview that she had, once again, attempted suicide that same day, Nov. 10, 2014.
