CODY, Wyo. (AP) — A Wyoming man accused of killing his wife is set to go on trial next month.

The Cody Enterprise reported Wednesday that the first-degree murder trial of Dennis Klingbeil is scheduled to begin at the Park County Courthouse on Aug. 5, the one-year anniversary of the deadly shooting of Donna Klingbeil.

Prosecutors plan to call more than two dozen witnesses to outline a history of fights between the couple and threats of gun violence.

Klingbeil's lawyers plan to argue that the shooting was an accident and Klingbeil should be charged with a lesser crime.

Klingbeil of Wapiti has remained in jail with a $10 million bond since his arrest last year.
