Research shows that most convicted sex offenders have committed many, many assaults before they are caught. Over two-thirds of offenders who reported committing incest also said they assaulted victims outside the family. Young victims who know, or are related to, the perpetrator are least likely to report the crime to authorities. This behavior is known as crossover. Sex offenders rarely commit just one type of offense.
Many offenders have NO official criminal record or sex crime history of any kind.
Sex offenders come from all backgrounds, ages, income levels, and professions. Sexual deviancy often begins in adolescence. Sex offenders usually do not commit their crimes impulsively. They usually careful plan their crimes. In Colorado, this supervision is called Sex Offender Management.
