Teen Mom's Fatal Mistake: Baby Dies After Fentanyl Mix-Up

A 9-month-old child in Nassau County, Florida, died after his 17-year-old mother allegedly put fentanyl in his bottle. The mother initially claimed ignorance about the incident but later confessed to filling the bottle with what she thought was cocaine. The substance turned out to be fentanyl, and the child had enough of it in his system to kill 10 people, according to the medical examiner's office. The mother is now facing charges of aggravated manslaughter and possession of a controlled substance. The investigation is ongoing.
