The three Americans who died from unknown causes at a Sandals Resort in the Bahamas have been identified.

Law enforcement released the names of the four people affected by an unidentified sickness. Three of the tourists were found dead on Friday, while the fourth was hospitalized and airlifted to a hospital in Miami, Florida.

The victims who died were identified as Michael Phillips, 68, Robbie Phillips, 65, and Vincent Chiarella, 64. Donnis Chiarella, Vincent's wife, was hospitalized but is in stable condition after being airlifted on Sunday. Michael and Robbie Phillips were both from Tennessee and ran a travel business called The Sand Lady from Royal Travel, according to Fox News.

The Chiarellas' son said his father was found dead on the floor and that his mother was unable to move due to swollen limbs, according to ABC News. They were at the resort celebrating an anniversary.

Samples have been collected from all of the victims and sent to a lab in the United States for further examination, according to the Nassau Guardian.

"We can confirm the death of three US citizens in the Bahamas," a State Department official said in a statement prior to the victims' identification. "We are closely monitoring local authorities' investigation into the cause of death. We stand ready to provide all appropriate consular assistance. Out of respect for the privacy of the families, we have nothing further to add at this time."

Resort staff alerted police around 9 a.m. Friday that two men and a woman were found unresponsive, according to press statements from the police. Police entered one villa and found a "Caucasian male lying on the ground unresponsive." Police were then directed to a second villa, where they found the second man "slumped against a wall in a bathroom unresponsive." The woman was "found in a bedroom on a bed."

The two people in the second villa showed signs of "convulsion," according to police, but none of the deceased people had signs of trauma on their bodies.
