Officials at Yellowstone National Park are searching for a man whose actions resulted in the death of a bison calf last weekend.
On May 20, a young calf became separated from its herd as the animals crossed the Lamar River. Rather than notifying a Ranger, a park visitor intervened and pushed the newborn up a slope and onto the road, where it began approaching cars and people. Rangers tried to reunite the calf with the herd, but their efforts failed and ultimately they took the difficult decision to put it down.
