Don Giacomo "Giacco" Magliozzi was the leader of Magliozzi crime family and the local Mafia, residing in Sacred Oaks. He was enemies with Wallenquist. He was uncle of Vito, Lucca and Andrea Vittoria Magliozzi. Once Bruno killed Andrea, and Magliozzi tortured and murdered people to learn who killed his niece. The Kraut did anything to cover Bruno's traces from that event. When Angie uncovered Bruno's past, Magliozzi went against his family's treaty with mob boss Wallenquist and ordered Vito to kill Bruno, who is on Wallenquist's payroll.
