YELLOWSTONE NATIONAL PARK, Wyo. (AP) — Yellowstone National Park officials killed a newborn bison because its herd wouldn’t take the animal back after a man picked it up.

The calf became separated from its mother when the herd crossed the Lamar River in northeastern Yellowstone on Saturday. The unidentified man pushed the struggling calf up from the river and onto a roadway, park officials said in a statement Tuesday.
