Costa Rican authorities have once and all confirmed that the son of Brett Gardner Miller died of inhaling carbon monoxide during a family vacation.
Mystery has surrounded the death of the 14-year-old since it was announced last week, with suffocation and food poisoning both excluded by examiners, and the hotel that claims that carbon monoxide poisoning was the cause.
But now the official toxicological report has been released, which confirms that Miller died as a result of exposure to carbon monoxide, after a saturation level of 64% was found in his room.
The report, released by Randall Zuniga – general manager of the OIJ – leaves on Wednesday, added that “concentrations above 50% are already deadly.”
He added: “In this case, the saturation rate is higher, which proves the hypothesis of the police that death was due to exposure to carbon monoxide.”
Zuniga also confirmed that the case has now been officially closed and revealed that tests had also returned negative results for other medicines.
