Investigation Into Death of Brett Gardner's Son Focuses on Food Poisoning and Medication

Authorities in Costa Rica have ruled out asphyxiation as the cause of 14-year-old Miller Gardner's death and are now examining food poisoning, medication, and other potential factors.

Miller Gardner, son of former MLB player Brett Gardner, died on March 21, 2025, during a family vacation in Costa Rica after falling ill with severe symptoms alongside his family.
Costa Rican authorities have ruled out asphyxiation as the cause of death, initially considered due to food intoxication, and are conducting further toxicology and autopsy tests.
Investigators are testing food samples from a local restaurant where the family dined, as food poisoning remains a primary focus of the investigation.
Authorities are also examining whether medication administered to Miller for his symptoms the night before his death could have contributed to the tragedy.
The Gardner family has requested privacy as they grieve and await answers, with full toxicology and autopsy results expected in two to three months.
