Police arrested Cunningham and Freund on Wednesday after showing them a “forensic analysis of cell phone data,” which allegedly led the pair to divulge “information that ultimately led to the recovery” of A.J.’s body, Crystal Lake Police Chief James Black said at a press conference Wednesday.

Both face a slew of charges including first-degree murder, aggravated battery and failure to report the death of a child, online court records show.
