Questioning by defense attorneys Wednesday led to suggestions that former child welfare workers did more to investigate an abuse allegation involving 5-year-old AJ Freund than was reflected in their reports.

       The cross-examination challenged prosecutors’ narrative that former Department of Children and Family Services investigator Carlos Acosta and his supervisor, Andrew Polovin, failed to prevent AJ’s death by abuse from his mother in 2019.

       Acosta and Polovin each are charged with child endangerment and reckless conduct, relating to their investigation of an incident that occurred about four months before AJ was fatally beaten at his home in Crystal Lake.
