Omaha police fatally shot a woman outside a Walmart after officers confronted her for allegedly taking a small child at knifepoint and cutting him, authorities said. Police say the suspect shoplifted a large knife inside the store, used it to seize the boy — described by officials as 2 or 3 years old and later reported as 3 — and forced the child's caretaker to walk ahead of a shopping cart while she followed with the child at knifepoint. As officers arrived and gave commands, the suspect began swiping the knife at the child, cutting him across the face and one hand; at least one officer fired, killing the woman at the scene. Body-camera stills released by police show the woman raising the knife over the child as an officer aims a gun. The boy underwent surgery for a significant facial laceration and a hand wound and is expected to survive, officials said.
