(AP) — A 58-year-old Nebraska man has pleaded not guilty to charges that he killed his former wife and his former divorce attorney.

Michael Petersen, of Glenvil, entered a plea Tuesday in Hall County District Court. He’s charged with first-degree murder and use of a weapon in the slaying of 52-year-old Todd Elsbernd. Prosecutors say Petersen shot Elsbernd on Nov. 13 outside his Grand Island law office.

Last week Petersen pleaded not guilty to the same charges in Buffalo County. He’s accused of killing his former wife, Nancy Petersen, on the same date at her rural Buffalo County home.

His trial is scheduled for May.
