North Dakota grandmother and 3 grandchildren shot

It looks like yet another mass shooting. This one is still under investigation but allegedly a grandmother and 3 of her grandchildren were shot in North Dakota. From an article:

A woman and three children were found Sunday afternoon, victims of “violent deaths,” said Kyle Loven, spokesman in the FBI’s regional headquarters in Minneapolis that includes North Dakota.

“We are looking at those deaths as homicides,” Loven said today.

The death of a man whose body was found in nearby Parshall, N.D., is being investigated “In connection,” with the New Town homicides, he said. “We are not looking at that death as a homicide,” he said.

But he would not say whether it appeared to be a murder/suicide situation.

"This is a very fresh investigation," Loven said. "We are confident there is no threat to the public at large."

Community members have said the woman and children died from gunshots, but Loven said he could not provide such investigatory details today.

The FBI has taken the lead largely because New Town and Parshall are on an Indian reservation, Loven said.

“Right now we are the lead agency, working in concert with the BCI and the BIA,” Loven said. “It really is a joint investigation.”

Any serious crime on an Indian reservation typically can involve the FBI’s jurisdiction, he said.

The woman has been identified as Martha Johnson. More information will likely become available.

Here is a related and more recent article about this shooting:

There authorities found four victims, a woman and three of her grandchildren, identified by the Mountrail County Sheriff’s Office as Martha Johnson, 64; Ben Schuster, 13; Julia Schuster, 10; and Luke Schuster, 6.

Neighbors said the 12-year-old boy who called 911, also Johnson’s grandchild, survived by playing dead, which New Town Police Chief Arthur Walgren confirmed.

About 7 p.m. Sunday, law enforcement learned a man had made statements about the crime.

While investigators were questioning him in Parshall, about 17 miles east of New Town, he killed himself with a knife, according to Sheriff Ken Halvorson.

Johnson was caring for five grandchildren, according to friends and neighbors.
