The Unit assists local law enforcement in a variety of investigations including child sexual abuse, child pornography, online enticement, and human trafficking. Supplemental information, such as phone numbers, email addresses, screen names, and handles are also required, but are not public. In addition, sex offenders must register with the County Sheriff any change of residential address, place of employment, or enrollment in a school or institution of higher education. Tier I Sex offenders must register with the County Sheriff at least once annually for a period of 15 years. The new reverse lookup feature is just another tool that parents can use to screen who their children are communicating with. Ohio is one of only eight states that offers this new sex offender reverse lookup feature. Parents still need to be cautious about who their kids are talking to in general. Tier III sex offenders may also be subject to community notification, which means upon a change of residential address, the County Sheriff will provide notice to a neighborhood within feet of the sex offenders residential address. Additionally you are encouraged to register to receive offender status alerts via email through our Sex Offender Alert System. In addition, must register any change of residential address, place of employment, or enrollment in a school or institution of higher education. So, parents need to keep communicating with their kids about letting strangers — virtual ones — in their circle of friends. The County Sheriff will also provide notice to schools, registered day-care providers, and law enforcement agencies within the county. This is also a useful feature for adults as well to know who they are communicating with. The reverse lookup feature now allows members of the public to input phone numbers, email addresses and internet names into the eSORN database and an alert will be displayed if the information is associated with a registered sex offender.
