Some details have come to light about the tragic death of Miller Gardner.

Former MLB player Brett Gardner and his wife Jessica Gardner announced their 14-year-old son died on March 21, with the U.S. Embassy of Costa Rica sharing that the family was vacationing in the country at the time. 

Now, just days later, Costa Rica’s Judicial Investigation Agency has shared information about Miller’s health in the hours leading up to his passing—including how all four Gardner family members may have gotten sick.

On March 20, Brett, Jessica and kids Miller and Hunter, 16, went to a restaurant outside of their hotel and felt ill when they returned, agency spokesperson Juan Pablo Alvarado Garcia told NBC News March 25. A medical team at their hotel treated both all four with medicine.

It was the next morning that Miller’s body was found in his hotel room in Manuel Antonio, according to the agency. 

Officials saw that the teen had vomit in his mouth and nose, so they initially believed that he had suffocated on his own throw-up. However, a forensic pathologist subsequently analyzed Miller’s body and did not find any obstruction in the airways, so they ruled out asphyxiation as his cause of death, according to Alvarado Garcia.
