The trial of a man who says he assisted in another man's suicide is set to get under way in Rapid City.

Jury selection was scheduled Monday in the trial of 51-year-old Robert Goulding of Rapid City. He is charged with first-degree murder in the shooting death last November of 56-year-old Allen Kissner of Redfield.

Authorities say Goulding has confessed to pulling the trigger.

Goulding's attorney says the shooting near Sheridan Lake was an assisted suicide, not murder. Prosecutors say they are confident they can prove murder.

Goulding's wife, Nancy Ellwein, was charged as an accessory to murder and pleaded guilty in May to misprision of a felony. She was given a one-year suspended sentence.
