The affidavit says Compass said she had checked her vehicle for her methadone medication to see if Zayden had taken any. She said he hadn't.
A search of Compass' vehicle unveiled an unlocked Avengers pencil box in the back seat. Inside that box were three bottles of methadone. The affidavit says one bottle was empty and two others had small amounts inside. That methadone was liquid and bright pink in color.
On June 3, a few days after Zayden's death Compass said he had about a cup of red Jungle Juice at the motel room. She denied that Zayden took her medicine and denied being involved in giving him any methadone.
