The State of California maintains a public database enabling you to search for names of registered sex offenders and information about them. You can also search by location, zip code, and some venues where children gather. The Megan's Law database is updated regularly and it is best to check your area every so often for any new offenders. The page has legal disclaimers and information you will need to review and agree to prior to conducting a search.
In addition to the Megan's Law information, the State website offers great advice and tips to parents on helping prevent our children from becoming victims of sexual assault.
"Inform children that it is wrong for adults to engage children in sexual activity. Stress to your child that he or she should feel comfortable telling you anything, especially if it involves another adult. If your child does not feel comfortable being completely honest with you, then together you should find another trusted adult your child can talk to in confidence. Make an effort to know the people with whom your child is spending time. Knowledge is power. This is especially true for protecting children from sexual assault..."
