CHEYENNE, Wyo. (AP) — Authorities say a Burns man told deputies he shot and killed his wife because she was yelling at their grandchildren.

Prosecutors allege 61-year-old Ronald Thomas Zimmerman shot and killed 51-year-old Teresa Zimmerman on Sunday at the family home in Burns, a small community about 30 miles east of Cheyenne.

The Wyoming Tribune-Eagle reports that Zimmerman appeared in Laramie County Circuit Court on Tuesday on a charge of second-degree murder.

Circuit Court Judge Denise Nau set Zimmerman's bond at $100,000 and scheduled a preliminary hearing for July 31 to decide if there's enough evidence for him to face charges in district court.

Prosecutors say Zimmerman told an officer of the Laramie County Sheriff's Office that he shot his wife in the face with a 12-gauge shotgun.
