NORTH PLATTE, Neb. (AP) - The Nebraska Game and Parks Commission says testing completed at Washington State University show as many as seven diseases contributed to the deaths.
The carcasses of about 8,500 common carp washed up on Sutherland's shorelines in June, as did less than 1,000 at Lake Maloney.
