The I-70 killer is an unidentified American serial killer who is known to have killed six store clerks in the Midwest in the spring of 1992. His nickname derives from the fact that several of the stores in which his victims worked were located a few miles off of Interstate 70 (I-70). Despite the case being featured on Unsolved Mysteries, America's Most Wanted, and Dark Minds, the killer is yet to be identified and investigators have not publicly identified any suspects.
