A young father of one with a second child on the way was beaten to death late last month outside a Chicago bar, and cops need help locating his killers. Blunt force trauma was the cause of death for Alexander "Xander" Kazanowski, who was found unresponsive on a street in the Chicago neighborhood of Avondale at 3:20 a.m. the morning of March 25. Local reports indicated Kazanowski, who worked as a model, was asked to leave a bar called the Tune-Up because of a number of off-color comments he had made. Kazanowski kept talking outside the bar to a group of four people who ended up jumping him.
