Miller Gardner's Death Confirmed as Carbon Monoxide Poisoning, Investigation Nears Completion

Costa Rican authorities identified a machine room near the hotel room as the likely source of lethal contamination, while the Gardner family mourns their tragic loss.

Costa Rican authorities confirmed Miller Gardner, son of former Yankees player Brett Gardner, died from carbon monoxide poisoning on March 21, 2025.
Toxicology revealed a carboxyhemoglobin saturation of 64%, far exceeding the lethal threshold of 50%.
Investigators believe the carbon monoxide originated from a machine room adjacent to the Gardner family's hotel room at the Arenas Del Mar Resort.
The hotel disputes claims of lethal gas levels in the room, though forensic reports are being finalized to close the investigation.
The Gardner family and the Yankees organization have expressed profound grief, with tributes honoring Miller's life and vibrant personality.
