A sex offender must register with the law enforcement agency having jurisdiction where they reside. If the offender lives within the city limits, he or she will register with the city police department. If the offender resides in an unincorporated area, he or she will register with the county sheriff's office.
If you know the location of a sex offender who is in violation of the registration requirements, you can contact the Lemont Police Department by calling (630) 257-2229.
