Lake County Judge George Strickland found Carlos Acosta, 57 of Woodstock, who was a case investigator for the Illinois Department of Children and Family Services, guilty of the child endangerment charge but acquitted him of a reckless conduct charge, related to the 2019 beating death of 5-year-old Andrew “AJ” Freund. Strickland said he could not find Acosta’s supervisor, Andrew Polovin, 51, of Island Lake, guilty of either charge because he did not know how much Polovin knew about the abuse of the boy.
