Randall Zúñiga, director of the Judicial Investigation Agency (OIJ) in
Costa Rica, has announced that inhalation of carbon monoxide is the primary hypothesis regarding the cause of death of Miller Gardner, the 14-year-old son of former New York Yankees player Brett Gardner.
Miller was discovered unresponsive in his hotel room in Manuel Antonio, Quepos, on March 31.
During a press conference on the same day, Zúñiga stated that investigators have established a 'fairly clear' line of inquiry into the circumstances surrounding the young boy’s death.
The investigation includes forensic engineering specialists from the OIJ and the Fire Department, who conducted tests in the hotel room where Gardner was staying.
High levels of carbon monoxide emissions were detected in the room.
Zúñiga noted that the measurements reached as high as 600 parts per million, a level significantly above the safe threshold, which is zero.
This alarming finding led investigators to consider that Gardner may have succumbed to the inhalation of these hazardous gases.
Adjacent to the room where Miller passed away is a mechanical room, which could be a potential source of the carbon monoxide leak.
Initial speculation regarding suffocation due to food poisoning was dismissed by the OIJ the following day.
Miller was on vacation with his family, including his brother Hunter and parents Brett and Jessica Gardner, when the incident occurred.
His death has prompted expressions of sorrow from across the baseball community.
Carbon monoxide poisoning, though not frequently reported in
Costa Rica, has occurred in past instances.
Symptoms of moderate exposure can include severe headaches, weakness, dizziness, nausea, vomiting, syncope, and tachycardia, while severe exposure can lead to seizures, pulmonary edema, respiratory failure, stupor, loss of consciousness, coma, and death.
Forensic toxicology results are pending to confirm the exact cause of death.
The investigation continues as authorities seek to clarify the circumstances leading to the tragic incident.
