NEW TOWN, N.D. — The Federal Bureau of Investigation has concluded its investigation into the November 2012 shootings deaths of a woman and her three grandchildren.
In a statement issued today, the FBI said Kalcie Eagle, 21, who had been identified as a person of interest, acted alone during the shootings in New Town and had methamphetamine in his system, according to autopsy and toxicology reports.
Eagle used a hunting rifle on Nov. 18, 2012, to kill Martha Johnson and her grandchildren Benjamin Schuster, 13, Julia Schuster, 10, and Luke Schuster, 6, in their home, the FBI said.
Eagle made statements to witnesses who were interviewed by the FBI admitting his responsibility for the killings. He also made statements to witnesses interviewed by the FBI that confirmed his possession of the hunting rifle.
Eagle died by suicide later the same day in the neighboring community of Parshall by cutting his throat with a knife.
Both towns are on the Fort Berthold Reservation in northwest North Dakota.
J. Christopher Warrener, special agent in charge of the Minneapolis division of the FBI, said in the statement that investigators conducted extensive interviews and collected numerous pieces of physical evidence.
“Many investigative hours were dedicated to this investigation in order to ensure that no additional threats to the community existed,” Warrener said. “We hope the conclusion of this investigation brings some closure to family members and the community.”
FBI spokesman Kyle Loven said investigators were unable to determine a motive for the shootings.
It took the FBI 11 months to issue the statement because investigators wanted to complete all aspects of the investigation to rule out whether Eagle received any outside assistance, Loven said.
“We wanted to make certain that there were no other parties that may have been involved in these killings,” Loven said.
