AceShowbiz - The official cause of death for New York Yankees player Brett Gardner's son, Miller, has been officially revealed. On Wednesday, April 2, authorities determined exposure to carbon monoxide as the main factor behind the 14-year-old's death.

Following these findings, Arenas Del Mar Beachfront & Rainforest Resort, the hotel where Miller and his family were staying, refuted the agency's conclusions. The hotel claimed that the levels of carbon monoxide in the room were "non-existent and non-lethal."

According to Randall Zuniga, director of Costa Rica's Judicial Investigation Department (OIJ), Miller, who passed away while his family was on vacation in Costa Rica, was tested positive for carboxyhemoglobin.

"A stable complex of carbon monoxide that forms in red blood cells when carbon monoxide is inhaled," as described by Medscape. A carboxyhemoglobin saturation level of over 50% is considered lethal, and Miller's level was at a staggering 64%.

During the autopsy, a "layer" was also found on Miller's organs, indicating the presence of the poisonous gas. Zuniga added, "It's important to note that adjacent to this room is a dedicated machine room, where it's believed there may be some type of contamination toward these rooms."

Miller's death was initially attributed to asphyxiation, potentially from food intoxication. However, these claims were ruled out, and the current investigations focus on hazardous atmosphere conditions. As of late March, Zuniga noted that a specialized "hazardous atmospheres" team found high levels of carbon monoxide in the room.

The loss has been extremely tough for the Gardner family. In March, Miller's parents the heartbreaking news on social media, With heavy hearts we are saddened to announce the passing of our youngest son, Miller."

"He was 14 years old and has left us far too soon after falling ill along with several other family members while on vacation. We have so many questions and so few answers at this point, but we do know that he passed away peacefully in his sleep on the morning of Friday, March 21st."

The investigation is still ongoing. Juan Pablo Alvarado Garcia from Costa Rica's Judicial Investigation Agency cautioned that due to a high demand for autopsies in the country, "The results are expected to be available in two to three months."

As the Gardner family navigates this unimaginable loss, they have requested privacy. Meanwhile, the search for answers continues in hopes of preventing such a tragedy from befalling other families.
