Miller is a senior wildlife veterinarian with Colorado Parks and Wildlife. Back then, local wildlife scientists were studying captive mule deer at a facility in Fort Collins, Colorado. They were trying to figure out how to help mule deer in the wild survive harsh winters, but the animals kept getting sick and dying.
