As per officials, Miller Gardner, a 14-year-old son of former New York Yankees outfielder Brett Gardner, died because of carbon monoxide poisoning. In a statement posted on YouTube, Rándall Zúñiga, the director of Costa Rica's Judicial Investigation Agency, OIJ, stated that tests revealed that the room Gardner stayed in while on vacation in Costa Rica had high levels of carbon monoxide.
"It's possible that the teenager could have died from "breathing in these gases that are so dangerous," added the official. The toxic gas could have come from a "specialized machine room" located next to the family's hotel room.
