WIND CAVE NATIONAL PARK (AP) — Four more cases of chronic wasting disease have turned up in Wind Cave National Park.

The fatal disease has been confirmed in three deer and one elk, park officials said.

The park has been monitoring deer and elk herds for several years, and information gleaned from the animals will help researchers better understand the disease, said Dan Roddy, the park’s resource management specialist.

Since 1998, 114 deer and 21 elk have been tested for chronic wasting disease. Of those, eight deer and four elk have tested positive.
