Finally arrested in 1990 after an Arizona state trooper approached Robert Ben Rhoads 18 wheel truck on the side of the highway, the Trooper Mike Miller had no idea he was stopping one of the worst serial killers of the 20th Century. With a mobile torture and murder chamber that he also used to make a living, Rhoads was able to traverse the country appearing to be one of the hard working drivers who supply us with all that we need. His route was different. He may have been arrested for three murders but he is suspected in the deaths of upwards of 50 women.
