Authorities now say a man who died while deer hunting in western Illinois was shot to death by his father in a likely accident. The Knox County Sheriff says 34-year-old Steven Hayworth Jr. of Washington died near Williamsfield. The sheriff said Hayworth was walking about 400 yards ahead of his father, 59-year-old Steven Hayworth, and another hunter trying to flush deer. Two deer ran toward the father who fired. The shot struck the younger Hayworth in the head. Officials say the father could not have seen his son because of the terrain. The older Hayworth was briefly hospitalized Sunday for unspecified reasons.
