Federal authorities say an Atlanta area woman bought the gun that was used to kill a police officer in Nebraska.

A statement from a federal agent filed last week in federal court in Atlanta says Jalita Johnson replied "yes" to a question on a form asking whether she was the actual buyer of the gun. In reality, the agent wrote, Marcus Wheeler gave Johnson money and told her which gun to buy for him. Wheeler was identified as her boyfriend.

Reached by The Associated Press at a number listed in court documents, Johnson said she had no comment.

Police in Omaha say Wheeler fatally shot officer Kerrie Orozco on May 20 when he opened fire on officers trying to arrest him. Wheeler was killed when another officer returned fire.
