Costa Rican authorities have revealed that carbon monoxide poisoning may have been the cause of death for 14-year-old Miller Gardner, the son of former New York Yankees star Brett Gardner, who died suddenly while on a family holiday last month.
The teenager was found unresponsive at the £710-a-night ($900) Arenas Del Mar Beachfront & Rainforest Resort in Manuel Antonio on 21 March, where he had been staying with his parents, Brett and Jessica Gardner, and older brother Hunter, 16.
