We tend to think of serial killers as a modern phenomenon. They are not. The first known serial killers in the United States were the Harpe brothers. Active in the late 18th and early 19th centuries, the Harpe brothers spread a path of terror across more than half a dozen American states. Along their way, they murdered between 39 and 50 men, women, and children. Their crimes, which often included grotesque mutilations, were so vicious that they made other murderers cringe with disgust. This is a true story, and it is as gruesome as any horror tale ever told. This fully documented story covers the lives of the Harpe brothers from their births until they met their ignoble ends.
