Wisconsin Sex Offenders

The State of Wisconsin established its own Sex Offender law on June 1, 1997. The law is also known as the Sex Offender Registration and Community Notification Law. The aim of establishing the law is to protect residents of the state from re-offending sex offenders.

The law ensures that persons convicted of a sexual crime in Wisconsin must register upon release from jail, parole, or probation. Also, the law mandates the state’s Department of Corrections to provide the details of sex offenders set to be free from prison.

The duration of registration is between 15 years and a lifetime. The length depends on the nature of the sex crime committed by the offender.

Sex offenders who have mental disorders which can lead to re-offend are “Sexual Predators”. These offenders go through a mental health facility upon release from jail.

Authorities monitor Sexual Predators closely, and they have to meet strict registration requirement in the state.

Sex offenders in Wisconsin verify their registration once every year. Also, any changes to the registered information must be reported to the Department of Corrections within 10 working days.

Wisconsin sex offender’s registry is in charge of all information on sex offenders in the state. The registry ensures that all registered information is accurate. This information is made available to the public through the registry’s official website.

What does a Sex Offender Look Like?

Most people think sexual predators are scary-looking and creepy. But three out of four adolescents who were sexually assaulted were victimized by someone they knew well.

Most of the time, sexual predators look like regular people. Children and parents need to know and to understand that anyone can be a sexual predator, no matter how "normal" they appear.

Encouraging Children to Share

It isn't always easy to build a trusting relationship with your child. Trying to get your children to share what is going on in their lives can be difficult.

Building an open and welcoming environment from the beginning stages of a child's life is essential. Children are less intimidated and more likely to discuss issues and topics in their lives with an open and supportive environment.

Getting your kids to share serves as a building block for times when your child needs to discuss pressing issues like sex and sexual abuse.
