SIOUX FALLS, S.D. — A shocking discovery in 1990 that a 9-year-old girl had been murdered began a 22-year legal and emotional saga that is expected to end Tuesday. Donald Moeller, who was convicted of abducting and murdering the girl, is scheduled to be put to death by lethal injection.

After decades of appeals, Moeller, 60, now accepts his fate. But the end leaves behind a community still marked by the crime and its experience with capital punishment.
