““Traditionally, most murders and violent crimes were relatively easy for law enforcement officials to comprehend. They resulted from critically exaggerated manifestations of feelings we all experience: anger, greed, jealousy, profit, revenge. Once this emotional problem was taken care of, the crime or crime spree would end. Someone would be dead, but that was that and the police generally knew who and what they were looking for. But a new type of violent criminal has surfaced in recent years—the serial offender, who often doesn't stop until he is caught or killed, who learns by experience and who tends to get better and better at what he does, constantly perfecting his scenario from one crime to the next. I say "surfaced" because, to some degree, he was probably with us all along, going back long before 1880s London and Jack the Ripper, generally considered the first modern serial killer. And I say "he" because, for reasons we'll get into a little later, virtually all real serial killers are male.””
