Miller Gardner Dies from Carbon Monoxide Poisoning, Confirmed Authorities

Miller Gardner, the 14-year-old son of former New York Yankees outfielder Brett Gardner, died from carbon monoxide poisoning while vacationing in Costa Rica, as confirmed by local authorities on April 2. Randall Zúñiga, the General Director of Costa Rica’s Judicial Investigative Agency, reported that a carboxyhemoglobin saturation level of 64 percent was found, significantly above the lethal threshold of 50 percent. This finding closed the case, ruling out other causes of death, including food poisoning or drug-related issues, as tests for various substances returned negative results. The family had initially expressed uncertainty around the circumstances of his death, but the toxicology report clarified that carbon monoxide exposure was the cause. Miller passed away peacefully in his sleep on March 21, leaving his family and community in mourning. The tragedy highlights the dangers posed by carbon monoxide, which can lead to severe health consequences in enclosed spaces.
