The death of three Americans at the Sandals Emerald Bay in the Bahamas was reportedly due to carbon monoxide poisoning. Minister of Health for the Bahamas, Dr. Michael Darville said health officials were satisfied that the deaths were isolated and there was no public health concern.

According to the Nassau Guardian the pathologist is expected to release the findings of the autopsy and toxicology report. The initial autopsies were completed earlier this month.

There was no sign of trauma to the bodies of the deceased.

Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate to dangerous levels. It can be particularly dangerous to people who are sleeping.

The deceased were identified as Michael Phillips, 68, and Robbie Phillips, 65, from Tennessee; and Vincent Chiarella, 64, from Florida. Chiarella’s wife was found alive but unwell and was airlifted to New Providence then transferred to a hospital in Florida. She has left the Miami hospital and is reportedly in good condition.

The two couples were staying in different villas next to each other at the Exuma resort.

Darville told the media that the victims’ families have requested a private pathologist conduct separate autopsies

Sandals has not as yet responded publicly to the report findings.
