Miller Gardner — the 14-year old son of former Yankees outfielder Brett Gardner — died from carbon monoxide poisoning, Costa Rican authorities confirmed Wednesday.
A blood test for carbon monoxide showed a saturation level of 64% in Gardner’s body, Costa Rican officials said. Concentrations above 50% are considered lethal.
Additional tests to detect the presence of drugs such as fentanyl were also conducted. Those results came back negative.
Gardner was found dead by a family member in a hotel room on March 21 while vacationing at the Arenas Del Mar resort in Costa Rica. Investigators found high emissions of carbon monoxide contamination in the hotel room where Gardner and his family were staying, OIJ director Randall Zuniga said during a video press conference on Tuesday.
The hotel room was next to a specialized machine room, which could have led to the contamination, Zuniga said.
The night before Gardner’s death, the family went out to dinner at a restaurant close to the resort and said they felt sick when they returned to the hotel, according to a Costa Rican source close to the investigation.
Miller was the youngest of the Brett Gardners’ two sons.
