ABERDEEN, S.D. — A 38-year-old Aberdeen man received a partially suspended 15-year prison sentence after he pleaded guilty to assault and drug charges.

Mattson was sentenced on felony charges of aggravated assault and possession of methamphetamine and a misdemeanor simple assault charge. He received a 15-year prison sentence on the aggravated assault charge with five years suspended. He must serve at least 75% of that sentence before he is eligible for parole. According to court documents, the simple assault was in August and the aggravated assault was in late November.

Mattson was accused of assaulting a woman with a baseball bat and a knife. Deputy State's Attorney Jodi Brown also said the door to the apartment was nailed shut preventing the woman from leaving, and she had to escape through the second-story window.

He also received a five-year suspended prison sentence on the drug charge and one year in jail on the simple assault charge. He was given credit for 294 days served. He was fined $300 and ordered to pay restitution of $26,944 to cover the cost of his mental health evaluation, reimburse victim services and cover medical expenses. All of the terms will be served concurrently.
