6. Matteo Messina Denaro
Denaro is a well-known mafia family. Matteo Messina Denaro inherits the family “business” from his infamous father, the Don Ciccio, Francesco Messina Denaro. He committed his first murder by the age of 18 and he bragged about it.
Matteo, also known as Diabolik, is a part of Cosa Nostra. This organization embarked on a terrorist campaign back in 1993 and Matteo played a prominent role. In order to force the Italian state to retreat, they conducted several bomb attacks in Italy. Ten people were killed and 93 others were injured as the result of those attacks.
After the bombings, Matteo went into hiding. He has never been seen ever since. And finally in 2002 even without his presence, he was sentenced to life.
Matteo is not really missing either. He is still running his family business, yet he has never been found by the law enforcement (or has he?). Up until today, he is still one of the most wanted fugitives in Italy, and in the world.
