Carbon Monoxide Poisoning Was The Cause Of Death For Former Yankees Of Brett Gardner's Teenage Son

Carbon monoxide poisoning was the cause of death of the teenage son of former New York Yankees outfielder Brett Gardner , authorities in Costa Rica confirmed Wednesday night.

Randall Zuniga, director of the Judicial Investigation Agency, said they tested the 14-year-old Miller Gardner for carboxyhemoglobin, a compound generated when carbon monoxide binds to hemoglobin in the blood.

When carboxyhemoglobin saturation exceeds 50, it is considered lethal. In Gardner's case, the test showed a saturation of 64.

"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," Zuniga said.

The head of the Costa Rican judicial police added that, during the autopsy, a "layer" was detected on the young man's organs, which forms when there is a high presence of the poisonous gas.
