Two men and one woman were found dead at the popular Sandals Emerald Bay resort on Exuma Friday, PEOPLE previously confirmed. A fourth person, a woman, was hospitalized.

Austin — who did not immediately return PEOPLE's request for comment — told ABC News that his mother visited a clinic after falling ill on Thursday, but that she "thought she was alright" after being released.
When she woke the following morning, "my dad was laying there on the floor, and she couldn't move," Austin told the outlet of his parents, both in their mid-60s.
"Her legs and arms was swollen and she couldn't move and she screamed to get someone to come in the door," he added.

Although a cause of death has not yet been identified, a representative for Sandals previously told PEOPLE there was "a health emergency."
"It is with deep sadness that we can confirm the passing of three guests at Sandals Emerald Bay on May 6, 2022," the hotel representative said in a statement.
"A health emergency was initially reported and following our protocols we immediately alerted emergency medical professionals and relevant local authorities," the statement continued.

The Royal Bahamas Police Force said Friday that authorities were informed that morning that three bodies were found in two separate villas at Emerald Bay.
"On their arrival at the scene they were directed to the first villa. On entering a bedroom, they found a caucasian male laying on the ground unresponsive. An examination of the body was conducted, there was no signs of trauma found. The local doctor later pronounced the victim dead," the RBPF said in a statement.
"The officers were then directed to the second villa, where they found a caucasian male slumped against the wall in a bathroom unresponsive. A caucasian female was also found in a bedroom on a bed. She too was unresponsive. Both individuals showed signs of convulsion," police continued. "The officers examined the bodies and found no signs of trauma. The local doctor later pronounced both persons dead."
Police said in the statement that their "initial investigations revealed that the couple found in the second villa complained of illness the previous evening." After "receiving treatment" at a local medical facility, the couple returned "to their lodging."
