The Dark Side of True Crime: Idaho's History of Unsolved Murders

After four University of Idaho students were found murdered in a house near campus last November, investigators used digital footprints and forensic evidence to search for leads. The case was solved using an advanced method of DNA analysis that had rarely been used in active murder investigations. Bryan Kohberger, a Ph.D. student from a nearby university, was arrested and indicted on four counts of murder. The process of identifying and arresting a suspect took over six weeks, and investigators have yet to detail a possible motive.
