The chief investigator for the medical examiner stated that the original placement of the duct tape was unclear and it could have shifted positions as he collected the remains.[6] Cindy Anthony testified that their family buried their pets in blankets and plastic bags, using duct tape to seal the opening.[83] Additionally, an FBI forensic document examiner found no evidence of a sticker or sticker residue on the duct tape found near the child's remains.[79][84]
