Was Bryan Kohberger's Murder of four college roommates inspired by Elliot Rodger? Rodger murdered six University of California, Santa Barbara students in 2014 with his arsenal of knives, pistols and his car as a weapon. Rodger, 22, was an incel, an "involuntary celibate," and continues to be seen as an icon by other incels. The incel connection is explored in a new documentary series: "One Night in Idaho," premiering on Prime Friday. #kohberger #idaho #truecrime #briankohberger | Inside Edition
