The FBI has wrapped up its investigation into the murder of a New Town woman and her three grandchildren.
The shooting happened in November 2012.
FBI officials say Kalcie Eagle shot and killed Martha Johnson and her grand kids Benjamin, Luke and Julia Schuster.
Authorities say Eagle shot them with a hunting rifle in their home and he acted alone.
The FBI says Eagle admitted his responsibility to the killings to witnesses before he killed himself in Parshall.
A toxicology exam revealed the presence of methamphetamine in Eagle's system.
