Anton was an associate of ruthless high-ranking Russian official Viktor Chagarin.
Anton was hanging out in the nightclub in Moscow. As he enjoying his time in the nightclub, CIA deep-cover agent John "Jack" McClane, Jr. comes in with a Makarov PM pistol and says that Chagarin's former partner Yuri Komarov sends his regards and goodbye before assassinating him. The guards then tackled Jack and arrests him for the assassination of Anton, which led to the string of events that involved Jack, his father John McClane and the weapons-grade uranium conspiracy. He is the first terrorist to die in the events, and the first to die by John McClane Jr's hands.
