In the past 30 years there have been over 500 identified killings along the busiest highways and interstates in the country.  At least 25 serial killers currently imprisoned for murder are truck drivers though the total number is limited only by the length of paved road stretching from coast to coast. The most infamous is  Robert Ben Rhoades, a sexual sadist who kept women in an area of his long haul truck he had outfitted as a torture dungeon. Rhoades is known to have murdered several but is suspected of over 50, maybe hundreds. We also cover Keith Jesperson, also known as the Happy Face Killer, who was convicted of killing 8 women across the country, though he insists the number is 160
