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 seven children.Pianetti opened a small restaurant where customers were also allowed to dance.
Because the local parish priest 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.
