A sex offender is a person that has been convicted of, or plead guilty to, an offense that involved sexual motivation. Each of these offenders are required to register with law enforcment agencies to stay in the community. Failure to reister is a punishable criminal offense. Ohio’s Sex Offender Registration and Notification law (S.O.R.N.), is designed to provide the public with adequate notice and information about those convicted sex offenders that have returned to the community. Most recently in 2007, the Ohio State Legislature passed Senate Bill 10, which implemented the Adam Walsh Child Protection Safety Act of 2006, a federal law which requires the classification of sex offenders into three tiers based on the severity of the offense. The specific tiers have been broken down below. These offenders must register their home, school, and work addresses, report any changes in addresses, and periodically verify addresses with the sheriff's office.
