An extensive encyclopedic reference guide to male and female serial killers from throughout world history. The World Encyclopedia of Serial Killers is the most comprehensive set of its kind in the history of true crime publishing. Written and compiled by Susan Hall, the four-volume set has more than 1600 entries of male and female serial killers from around the world. Defined by the FBI as a person who murders 3 or more people over a period of time with a hiatus of weeks or months between murders, serial killers have walked among us from the dawn of time as these books will demonstrate. While the entries to these volumes will continue to grow—the FBI estimates that there are at least fifty serial killers operating in the United States at any given time—The World Encyclopedia of Serial Killers is as complete as possible through the end of 2017. The series continues with Volume Two, E-L. The entries include El Loco Luis Alfredo Garavito, Happy Face Killer Keith Hunter Jesperson, Interstate Killer Larry Eyler, Godfather of Matamoros Adolfo de Jesus Constanzo, and Golden State Killer Joseph James DeAngelo. You will find these killers and approximately 350 others in this second book in the series of The World Encyclopedia of Serial Killers.
