This case is so odd. How can you test positive for substances in the urine but the toxicology reports post mortem say there wasn't? I can't quite wrap my brain around this.

Twelve-year-old Mya K. King was found unresponsive by her mother in the bedroom they shared on a Sunday morning in April 2024 and died three days later on April 17, 2024, after being transferred to a children’s hospital in Chicago. First responders administered CPR and Narcan at the scene; an initial hospital urine screen was positive for fentanyl. Officers found suspected heroin and fentanyl inside the mother’s purse in the same room, and 35-year-old Colette Bancroft was taken into custody on a possession charge and later released with a notice to appear in court. The Illinois Department of Children and Family Services was notified.

A Cook County Medical Examiner report in the fall of 2024 complicated the picture: postmortem toxicology on Mya’s blood was negative for all substances, so the examiner ruled both cause and manner of death undetermined. The Joliet Police Department says the investigation remains active and detectives are consulting with the Will County State’s Attorney’s Office; as of late 2024 no additional charges related to Mya’s death had been filed.

What information might help resolve the conflicting toxicology results or clarify what happened that April morning?
