Watch: "I almost lost him" - Parents react to woman's alleged attempt to kidnap son

A knife-wielding woman was fatally shot by police outside a Walmart in the US state of Nebraska after she kidnapped a child, police said.

The assailant abducted a three-year-old boy out of the Omaha supermarket at knifepoint on Tuesday in an apparently random attack, police said. Footage from officers' body-worn cameras showed her wielding the weapon at the child.

Police said she refused to drop the blade, and that she cut the boy's cheek before two officers fired at her.

The suspect, Noemi Guzman, 31, who had a history of mental illness, was pronounced dead at the scene.…
