Simone Pianetti (born 1858) was an Italian anarchist and mass murderer.
Pianetti was born in Camerata Cornello, Lombardy. At a young age, he unsuccessfully attempted to kill his father over a legacy question. For unknown reasons he was not charged and in an agreement with the local chief of the Carabinieri, he left Italy and went to the United States of America. After some years in the US he returned to Italy with a ticket paid for by his father.
Back in his village, he married a woman named Carlotta who gave birth to nine children.
Pianetti opened a small restaurant where customers were also allowed to dance. Because the local pastor and other church people did not agree with dancing in Pianetti's restaurant, the municipality forced him to close it. He subsequently opened an electric powered mill which was also unsuccessful.
Pianetti was the only person in the village who did not attend church on Sundays. He had grown to think that everyone in Camerata Cornello hated him, which supposedly led him to his killing spree.
On the morning of 13 July 1914, Pianetti used his rifle to shoot and kill 7 people:
- Domenico Morali, doctor
- Abramo Giudici, the manager of the municipality
- Valeria, daughter
- Giovanni Ghilardi, shoemaker
- Stefano Filippi, priest
- Giovanni Giupponi, a layman.
- Caterina Milesi, a farmer
Soon after the killings, Pianetti left the village and reached Monte Cancervo, where he lived for some days, despite a search by 200 people from the Carabinieri, the Polizia di Stato and a company of the 78th infantry regiment. Pianetti fired at some Carabinieri to escape into the mountains near the villages of Olmo al Brembo and Cassiglio. He was never arrested and his body was never found.
