An Aberdeen man was sentenced Wednesday on two incest-related charges. 60-year-old Gregory Rutherford pleaded guilty to avoid additional charges in up to four different counties. Authorities allege Rutherford engaged in a sexual relationship with his step-sister’s daughter for approximately seven years. Brown County state’s attorney Chris White requested the judge sentence Rutherford to the maximum 15 year sentence and he serve that sentence consecutively with a sentence in Brookings county. The judge agreed, but suspended five years from the sentence and gave Rutherford credit for eight days served.
