Tragic Loss: Brett Gardner's Son Dies from Carbon Monoxide Poisoning

14-year-old Miller Gardner, son of ex-Yankees player Brett Gardner, tragically lost his life to carbon monoxide poisoning while vacationing with his family in Costa Rica. An investigation revealed potential safety oversights at the resort, prompting discussions on precautionary measures for travelers.

Miller Gardner, cherished son of former New York Yankees standout Brett Gardner, passed away on March 21, 2025, due to carbon monoxide poisoning, as confirmed by Costa Rican officials. The investigation revealed dangerously high levels of carboxyhemoglobin in his bloodstream, suggesting critical carbon monoxide exposure. In a statement from Randall Zúñiga, director of the Costa Rica Judicial Investigation Agency, it was noted that Miller's saturation level reached a staggering 64 percent, well above the lethal threshold of 50 percent.

The family was vacationing in the picturesque Manuel Antonio resort area when the tragedy struck. A statement from the family indicated that Miller fell ill alongside several relatives during their stay. They shared that he "passed away peacefully in his sleep," expressing their grief over the sudden loss of a young boy who loved sports and family.

Costa Rican authorities noted that Miller's family was residing near a room containing maintenance machinery, leading to concerns regarding possible contamination. The luxurious Arenas Del Mar Beachfront & Rainforest Resort has yet to respond to inquiries regarding the incident following the toxicology findings, which have raised safety questions about the resort's operations.

Brett Gardner, who spent his entire MLB career with the Yankees from 2008 to 2021, was a beloved figure in the sport, known for his contributions to the team's 2009 World Series championship. Miller's passing has left a significant impact on the Gardner family, who also has a 16-year-old son, Hunter. As condolences pour in from fans and fellow players alike, the tragic incident serves as a reminder of the need for heightened safety standards in accommodations catering to families seeking leisure and adventure.
