“We serial killers are your sons, we are your husbands, we are everywhere. And there will be more deaths among your children tomorrow. (Ted Bundy). Serial killers are not always people who look like monsters or behave strangely. Sometimes they are successful people, those who have families and jobs. The term "Serial Killer" was first coined by Robert Ressler, former director of the FBI's Violent Criminal Apprehension Program.
