The Federal Bureau of Investigation as well as both local and state law enforcement agencies maintain annual reports which explain the crimes that have occurred each year per jurisdiction, specifically the number of murders in North Dakota by year. In addition to law enforcement and investigation agencies, Project: Cold Case, in partnership with the Murder Accountability Project, has put together a comprehensive list of the unsolved homicide statistics per state on their website. According to this website, between 1980 and 2019 there were only 508 murders in North Dakota. Since then, around 424 of those homicides have been solved, leaving the state with only 84 unsolved murders. According to Project: Cold Case, North Dakota has the least unsolved homicides remaining from 1980-2019 out of any U.S. state, with Wyoming not too far behind, with only 137 unsolved murders.
Due to the fact that there aren’t many unsolved murders in North Dakota, there aren’t many murders in any specific part of the state. The 1981 murder of Clifton Wendell Marsh, the 1994 murder of Ronald Johnson, the 2007 murder of Anita Knutson, and the 1985 suspicious death of Olivia Lone Bear are a few examples of the murders in northern North Dakota which remain unsolved today. Additionally, the 1963 murder of Larry Phebus, the 1972 murder of Lora Jean Dugan, the 1974 murder of Daniel Erick Johnson, the 1991 murder of Joseph Anderson, and the 2002 murder of Russell Douglas Turcotte are a few examples of unsolved murders in central North Dakota.
As for those in a more populated portion of the state, cases included within the category of murders in Bismarck, North Dakota, as well as murders in Burleigh County, North Dakota, which remain unsolved include the 1994 disappearance of Michelle Julson, the 2011 disappearance of Christopher Mann, and the 1996 disappearance of Sandra Jacobson and her son John Jacobson, among few others.
