This type of offender, called a situational child molester, does not possess a genuine sexual preference for children. Rather, the motivational factors are criminal in nature. In some cases, the offender's sexual abuse of young people is a natural outgrowth of other forms of abuse in his life. That abuse is a continuation of a process by which he has mistreated his friends, colleagues, spouse and family members. He will have low self-esteem, maintain poor moral standards and view sex with children as an opportunity to prolong the violence that is already an active component of his existence. Other situational offenders see children as a substitute for an adult partner. Although these types of offenders do not harbor a singular sexual desire for children, they may react to a built up sexual impulse or anger, that to them, is irresistible. However, the victim is incidental. It could have been a store clerk, an elderly person or simply a woman walking down a lonely street. Because of the circumstances at hand, such as the Polly Klass incident, the victim happened to be a child. His main criteria for a victim is availability. The situational child molester will usually have few victims, sometimes only one, and never repeat the event again. He could be a social misfit or a psychopathic personality who harbors a seething resentment and hostility toward society in general.
