As stated before serial killers are very methodical at what they do and they are always very careful at leaving clues behind. Most individuals clean up after they have committed a murder to make sure nothing is left behind unless they want it left behind. So if they escape police over and over again they start to feel as though they are invincible and the more dangerous the game becomes. It is very difficult for police to catch these killers because they are so careful at what they do. This is why serial killers are such a plague on society because new ones pop up everyday, and the police have a very difficult job to apprehend them.
Most serial killers have certain characteristics in common in very early childhood.
There are three characteristics that most serial killers share. These are supposedly warning signs in early childhood for individuals that may have that behavior start in adulthood. For most children bed-wetting is a common occurrence but when it persists into late childhood there could be a problem. When it comes to fire-starting, all children display a fascination with fire but when it becomes juvenile delinquent behavior then it becomes a problem. As these characteristics show early serial killers show a disregard for the normalcy of life and a flagrant hatred of all the rules of society.
