Hawaii man pleads guilty in Yellowstone bison calf death.
Clifford Walters, a Hawaii man, pleaded guilty to disturbing wildlife after he tried to help a stranded bison calf reunite with its herd in Yellowstone National Park, which ultimately led to the calf's death. The calf had been separated from its mother, and park rangers repeatedly tried to reunite them, but the herd resisted. The calf was later euthanized by park staff because it was causing a hazardous situation by approaching cars and people along the roadway. Yellowstone has a policy of not rescuing and rehabilitating animals, and it is illegal to transport bison out of the park unless they are going to meat processing or scientific research facilities.
