8. Axeman of New Orleans
Number of Victims: at least 12
As the name would imply, victims of the Axeman who ranks 8th in our list of most successful serial killers who have never been caught, were often killed with an ax that belonged to the victim. Some of the other victims were killed using a straight razor and police could not trace the pattern of the kills. In one case, a letter was sent to the police stating that the Axeman would spare the life of those who played jazz music in the city leading to a night filled with jazz music playing everywhere. There were no murders that night and eventually the murders mysteriously stopped.
