Toxicology Results Confirm Miller Gardner’s Cause of Death!
The tragic passing of 14-year-old Miller Gardner, the son of former New York Yankees star Brett Gardner, shocked the world and left many questions unanswered. After weeks of uncertainty, Costa Rican authorities have confirmed the cause of death. The heartbreaking truth was revealed through toxicology results: Miller died from inhaling carbon monoxide during a family vacation in Costa Rica.
Toxicology Results Confirm the Cause of Death
On Wednesday, Costa Rican officials made the devastating announcement that Miller Gardner’s death was caused by carbon monoxide poisoning. The country’s Judicial Investigation Agency confirmed that the young boy’s toxicology report showed a dangerously high concentration of carboxyhemoglobin—64%, which is far above the lethal threshold of 50%.
Randall Zúñiga, the director of the agency, explained in a statement, “The saturation percentage is higher, thus proving the police’s hypothesis that the death was due to exposure to carbon monoxide.” With the results now in, authorities have closed the case, providing a final answer to the mystery surrounding Miller’s death.

What Happened That Day?
Miller was found dead on March 21 at the Arenas Del Mar Beachfront & Rainforest Resort in Costa Rica. His family had been vacationing there when Miller suddenly fell ill under mysterious circumstances. Despite efforts to save him, he was declared dead after first responders tried to resuscitate him. Dr. Kevin Gannon, who was involved in the emergency response, shared that when they arrived, Miller had no vital signs. They performed CPR for 30 minutes, but tragically, it was too late.
In the wake of his passing, the Gardner family revealed their deep sorrow. In a statement shared by the New York Yankees, Brett and his wife, Jessica, described their loss as “unimaginable,” adding that Miller had “passed away peacefully in his sleep” after he and several other family members became ill during the vacation.

The Hotel’s Role and Initial Confusion
In the days following Miller’s death, local authorities began investigating the circumstances. Investigators soon detected “high levels of carbon monoxide contamination” in the family’s hotel room. A key theory was that the contamination had come from a nearby mechanical room.
However, the hotel initially denied the carbon monoxide theory. They argued that the levels in the guest room were “non-existent and non-lethal,” clarifying that the high readings were found in a “mechanical room” that guests do not occupy. Despite the hotel’s statement, authorities took the necessary precautions and closed off the room until the cause of death could be fully confirmed.
At first, other causes were considered. Some speculated that Miller might have suffered from an allergic reaction to medication, while others believed food poisoning or asphyxiation could have been responsible. But as toxicology results came in, those theories were ruled out.
Final Goodbye
As the toxicology results made it clear that carbon monoxide poisoning was the cause, the authorities closed the case. Meanwhile, Miller’s body was released to his family, and funeral arrangements began. A private celebration of life will be held in South Carolina, as announced in Miller’s obituary.

The Gardner family’s loss is immeasurable, and their grief is shared by many who followed Brett Gardner’s career and the story of this tragic event. While the answers about Miller’s cause of death have now been provided, the family’s sorrow remains.
A Sudden and Unthinkable Tragedy
The death of Miller Gardner is a tragic reminder of the dangers of carbon monoxide exposure, which can be silent and deadly. It’s an event that has shaken a family, a community, and fans around the world. As the Gardners move forward through their grief, the rest of the world watches in quiet sympathy, hoping that they find peace after such an unimaginable loss.
