Authorities are likely to euthanize a mother grizzly bear suspected of killing a hiker in Yellowstone. The bear was likely protecting her two young cubs when the hiker entered her territory. Authorities say they will also euthanize her cubs if they can't find a suitable home for them.
The hiker was invading the bear's territory. The bear was defending her young. If this were a story about a human mother protecting her children, we'd be calling mom a hero.
