SISSETON, S.D. (AP) – Authorities say a 22-year-old man apparently shot and killed three people and wounded a fourth at a home on a South Dakota Indiana reservation before he killed himself.

The state attorney general’s office said in a news release that the attack happened early Saturday at a home in the town of Sisseton. That’s on the Lake Traverse Indiana Reservation in the northeast corner of the state near South Dakota’s borders with North Dakota and Minnesota.

The attorney general’s office identified the alleged attacker as 22-year-old Colter Richard Arbach, who was from Sisseton. It didn’t identify the victims or say how they knew Arbach.

A Sisseton hospital official says a woman wounded in the attack was flown to Fargo hospital and is in stable condition.
