The profile of a serial killer, who they are and why they kill, has changed over the years.
American culture and its urban settings, streets of prostitution, homeless and lost people, will continue providing the victim pool for serial killers.
At the turn of the 20th century, America was on the move; it was changing from a country of farmers and small towns into a nation of growing urban centers.
After surviving the Great Depression and World War II, America entered an idyllic age, The Atomic Age, where wholesome values and classic Americana were king.
There was a golden age of female serial killers in the U.S. and Europe; female serial killers that targeted their children, husbands, and other family members.
There's been a long-held belief in the public that serial killing is largely an American phenomenon.
