Commander Tom Ross says Obzera apparently didn't meet the boys, aged 13 to 17, through her job. He says there's no indication the alleged abuse occurred on school property.
Officials say Bolingbrook police joined a Department of Children and Family Services inquiry into sexually charged text messages between a woman and teenage boys.
Obzera was released Thursday on $50,000 bail. It's not clear if she has an attorney and no one answered the telephone at a Bolingbrook number.
