The so-called "Golden Age of Serial Murder" lasted from 1970 to 1999. About 80% of all known serial killers operated during that period. Which makes Antone Charles Costa, usually known as Tony, ahead of his time: He killed at least two and probably eight women between 1966 and 1969. The circumstances of their deaths were strange, and fake news generated around his arrest made those circumstances seem even worse than they were. As a result he earned several colorful nicknames, like "Chop Chop" or "The Cape Cod Casanova." But the name that really stuck was most horrifying of all: "The Cape Cod Vampire."
