Cooper was filling in for Prime Minister Philip E. Davis, who was out of the country.

The head of communications for the prime minister's office, Latrae L. Rahming, tweeted that the deaths occurred at Sandals Emerald Bay in Exuma.

In a statement to People Magazine, a representative for Sandals confirmed the deaths and said the company was “actively working to support both the investigation as well as the guests' families in every way possible.”
