A now-closed criminal investigation into a former Crystal Lake South teacher who was accused of having an inappropriate relationship with a student was tied to a related Illinois Department of Children and Family Services investigation.
Former teacher and coach Jay Mueller submitted his resignation as a Community School District 155 employee on Aug. 9. Mueller’s resignation came on the heels of a Crystal Lake Police Department investigation that never led to charges.
The school district’s internal investigation into the claims included several meetings, telephone conversations and emails with Mueller, as well as the review of related DCFS records, district emails show.
The former head girls soccer coach and chemistry teacher last met with district officials for an “investigatory meeting” on July 25, district emails show. On July 9, District 155 Assistant Superintendent of Human Resources Jay Sargeant submitted a Freedom of Information Request to DCFS seeking the “complete investigative report” tied to Mueller’s conduct, according to district emails.
DCFS’ FOIA officer, Bret Angelos, responded to Sargeant’s request that same day. In the email, Angelos told Sargeant the district didn’t need to submit a FOIA request to obtain the records, and notified him that a DCFS supervising attorney would would be in touch.
The Crystal Lake Police Department has closed its investigation and does not expect charges to be filed against Mueller.
