NAPERVILLE, Ill. (AP) – A prosecutor has determined that a suburban Chicago police officer who fatally shot a hatchet-wielding man during a June traffic stop was justified in the deadly shooting. DuPage County State’s Attorney Robert Berlin said Monday that Naperville police Officer Frank Tonkovich “reasonably believed” 28-year-old Edward Samaan of Naperville was trying to kill either him or a driver Tonkovich had pulled over separately. The Daily Herald of Arlington Heights reports that Berlin said in a news release that Tonkovich’s actions were not just reasonable “but necessary in order to prevent great bodily harm or death to himself or the motorist he had stopped.”
