Further details of what caused the deaths of three guests and the hospitalisation of another at a Sandals resort last week are expected to be revealed today.

The results of an autopsy on at least one of the people who died are expected later today, when police will also officially name the guests who lost their lives.  

All four were Americans staying at the Sandals Emerald Bay resort in Exuma, and were found on Friday.

Three of the victims had reported feeling ill the previous night and had sought medical assistance.

There is speculation their deaths could have been caused by faulty air conditioning. 

Hotel staff found one man’s body shortly after 9am Friday in his villa and called police, who were then informed a couple in another villa had also been found unresponsive. All three were later declared dead.    

The wife of one of the men who died has been airlifted back to Florida for further medical treatment and is in intensive care, according to a family member.

Florida police said it is ‘closely monitoring local authorities’ investigation into the cause of death’, while Sandals said it is cooperating with the investigation, adding: “Nothing is more important to Sandals Resorts than the safety of our guests.”

Sandals added: “A health emergency was initially reported and following our protocols we immediately alerted emergency medical professionals and relevant local authorities. 

“We are actively working to support both the investigation as well as the guests’ families in every way possible during this difficult time.”
