Mario Spezi
Mario Spezi (July 30, 1945 – September 9, 2016) was an Italian journalist, author, illustrator, and caricaturist. He wrote the non-fiction true crime books Dolci Colline di Sangue (2006) and "Il Mostro di Firenze" (1983). He was a co-author in the book "The Monster of Florence A True Story (2008)" with American author Douglas Preston. Additionally, he was credited by Preston for providing details used in the novel "Brimstone". Spezi spent much of his career as a crime reporter for the La Nazione newspaper in Florence, where he reported on the case of the notorious serial killer  known as the Monster of Florence. He even spent 23 days in prison on charges of impeding the investigation by prosecutor Giuliano Mignini, though the charges were overturned on appeal. It was later decided that he was jailed illegally and without ample evidence of a crime. Later, Spezi even apologized to Amanda Knox and Raffaele Sollecito in the case of the murder of Meredith Kercher, another of Mignini's cases. Spezi also wrote the film "Il Mostro Di Firenze" (1986), based on his novel. The film aired in Italy and the United States. Spezi was a Roman Catholic. As a  result of a long illness, Spezi died on September 9, 2016. Following his death, Mediaset, an Italian mass media company, described Spezi as journalist who was "able to tell a story and analyze the facts by digging deeper in places where other journalists were afraid to look."
