Officers left a bright orange hang tag on the homes of those who were not home. They say it will notify the offender of their visit and serve as a warning to any trick or treaters who might stop by.
"We try to aggressively go out at times of the year when children are more likely to be going out and knocking on stranger's doors and to alert people who have been convicted and people who are on sex offender lists that you're not to be interacting with children and that you have prohibitions you need to follow and we're watching," said Sheriff Tom Dart, Cook County.
Dart encourages parents to check the sex offender registry on line (www.isp.state.il.us/sor) before taking their children out at a Halloween.
