The Illinois State Police maintain an online database of 15,000 registered sex offenders residing in the state. The information includes offender's name, address, ZIP code, date of birth and the age of the victim. The database is searchable by city or county of residence and ZIP code.
Users can also download lists of sex offenders into their computer.
The state police say they will add photographs of each offender at a later date. The Chicago Police Department maintains a list of registered sex offenders. The list is accessible by the user clicking on an area of the city. The listing provides the offender's name, block and street of residence, physical characteristics, date of birth, photo, and whether the victim was under 18. The Belleville Police Department provides a link on its Web site to the St. Clair Sheriff's Office database of registered sex offenders.
