Vladimir Kovačević Tref

Vladimir Kovačević, commonly known as Tref, was a prominent figure in the Serbian underworld during the late 1990s and early 2000s. He gained notoriety not only for his connections with organized crime but also for his marriage to Bojana Bajrušević, which attracted media attention. His life was cut short when he was murdered in 2003, but he remains a significant figure in discussions about the Zemun Clan's activities and influence in Serbia.
