Sharpshooters plan to cull the deer population in Boone County as part of attempts to control a fatal deer disease in northern Illinois.
The sharpshooters will be hunting in several conservation areas along the Kishwaukee River near Belvidere through the end of March.
The state Department of Natural Resources says testing has now found 41 cases of chronic wasting disease in Illinois, mostly in Boone and Winnebago counties.
Sharpshooters in Winnebago County have already killed about 100 deer, including two that recently tested positive for the disease. The carcasses of infected animals are destroyed, but those that test negative are donated to food pantries.
Chronic wasting is a fatal neurological sickness that causes infected animals to become emaciated and die. It isn't known to be contagious to humans or livestock.
