Between 1967 and 1969, terror gripped two college towns in Ypsilanti and Ann Arbor, Michigan, as investigators discovered the mutilated corpses of seven young women and girls. The murderer -- called the Coed Killer by newspapers of the time -- seemed to be so brazen that he was taunting police by returning to crime scenes and leaving behind evidence. The horrified public became so outraged that they took matters into their own hands by hiring a supposed psychic they hoped would finally crack the case.
