A serial killer is someone who murders two or more individuals at different times. For example, if a man murders a prostitute on Easter Day, kills another on Mother's Day, and then another on Memorial Day, then he will be classified as a serial killer. Types of serial killers The medical killer This type of killer is very rare. . This killer believes he has a clear alibi because he works in the medical profession. Therefore, whenever people die in hospitals, it does not necessarily look like murder. They make the death appear to be a natural cause so that no one expects the victims to have been murdered. The Organized Killer This type of serial killer is the most difficult to identify and capture. These killers are organized and intelligent. Organized killers carefully plan every detail in advance and ensure that no evidence can be attributed to them. These serial killers will stalk their victims until they find the one they want and lure them in with some sort of scheme. Finally, after searching for their victims, they take them to another location to commit the crime. The Disorganized Killer These individuals rarely plan the deaths of their victims in any way. These killers attack wherever they can. They are not trying to cover up the crime they committed. Instead of cleaning up their evidence, they prefer to move to different locations to avoid capture. http://www.crimemuseum.org/crime-library/types-of-serial-killersMotives of Serial KillersThe motivations of a serial killer are separated into four sections: visionary, mission-oriented, hedonistic, and power/control.
