Authorities later attributed his death to carbon monoxide poisoning. Those are two different stages of the investigation: the first was a preliminary finding about his respiratory tract; the second was the later reported cause of death.
What happened to Miller Gardner?
Miller Gardner, the son of former New York Yankees outfielder Brett Gardner, died on March 21, 2025, during a family vacation in Costa Rica. Costa Rican authorities later reported that testing found carboxyhemoglobin and attributed his death to carbon monoxide poisoning. MLB.com/Yankees
Why was asphyxiation initially ruled out?
On March 25, Costa Rican police told ABC News that asphyxiation had been ruled out because the respiratory tract was clear. The preliminary statement from Costa Rica’s Judicial Investigation Agency (OIJ), reproduced by CBS/AP, said that examiners observed no “macro-level anomalies” in the respiratory tract during their inspection of the body. ABC News CBS/AP
That observation addressed the initial asphyxiation theory; it was not, on its own, a complete explanation of the death. On April 2, as reported the next day, Costa Rican authorities identified carbon monoxide poisoning as the cause after testing detected carboxyhemoglobin, a substance formed when carbon monoxide binds to hemoglobin in the blood.

What happened in the investigation afterward?
September 2025: Costa Rican inquiry continued
In September 2025, prosecutors said proceedings were aimed at determining whether negligent homicide had occurred. The Associated Press reported that investigators raided the resort again to gather evidence related to the autopsy and that no one had been charged at that time. MLB.com/Yankees had earlier reported OIJ director Randall Zúñiga’s account of a “dedicated machine room” adjacent to the family’s room and the possibility that contamination reached the rooms. These were investigative statements, not findings of legal liability. Associated Press MLB.com/Yankees
March 2026: family lawsuit filed in Philadelphia
On March 20, 2026, the AP reported that Brett Gardner and relatives filed a negligence and wrongful-death lawsuit in federal court in Philadelphia. The report described the family’s allegations about ventilation at the resort; those claims are not adjudicated findings. The reporting available here does not establish later developments in that lawsuit or the current status of the Costa Rican investigation. Associated Press
