(AP) — A man accused of killing four people in Omaha last summer has argued that a county attorney unlawfully released information about the case to a local newspaper.

Nikko Jenkins questioned Douglas County Attorney Don Kleine during a hearing Wednesday. A judge later ruled there was no patient or client misconduct, and there was no evidence against Kleine. A motion to remove him from the case was overruled.

The 27-year-old Jenkins is charged with four counts of first-degree murder in the August shooting deaths of four people. He has pleaded not guilty, and claims he didn’t receive proper mental health treatment while previously in prison.

Jenkins is acting as his own attorney in the case, which has been scheduled to go to trial in July.
