Asphyxiation was ruled out as the cause of death of Miller Gardner, the 14-year-old son of former New York Yankees outfielder Brett Gardner. Authorities concluded that Gardner didn't die from asphyxiation because his respiratory tract was clear, police said. This comes a day after a Costa Rican government official had said Miller Gardner may have died from asphyxiation due to food poisoning. #brettgardner #yankees #nyyankees #newyorkyankees #MLB #costarica
