NEW TOWN, ND (CBS/KXMC) -- A woman and three of her grandchildren were shot and killed in New Town, North Dakota Sunday afternoon, and the death of a man in nearby Parshall later Sunday may have been related to their murders.
That's what law enforcement officials say following a violent day in those two Mountrail County communities.
The New Town police chief says the murders happened on 6th Street in New Town about mid-afternoon Sunday. He says a vehicle was seen nearby and a statewide search turned up the vehicle and its driver, but it turned out to be unrelated to the case.
Meanwhile, investigators figured out the suspect in the killings was a member of the Three Affiliated Tribes, so the investigation was turned over the FBI.
FBI officials won't say if the death reported last night in Parshall, about 15 miles away from New Town, was related to the murders. But sources tell KXMC it appears to have been the suspect and for that reason there is no concern about the safety of the general public.
New Town police chief Arthur Walgren says, "Chief of Police in New Town )"Whenever you have something of this magnitude happen it can really jar you as a community no matter what the size and when you are a smaller community like this it really puts a scare into people so...it is good that we have figured out who we think was involved in this and that there is no outstanding suspects at this time that we are aware of. "
Meanwhile, the superintendent of the New Town School called off school Monday since the three children killed all attended New Town elementary and middle school.
And, even though he had no official information to help in making a decision, decided not to hold classes.
