Three young women from Massachusetts who were found dead at a beach resort in Belize had a build-up of fluids in their lungs, according to reports.

The cause of death for each of the three Revere women who were found dead in their Belize hotel room has been announced by officials to be an “acute pulmonary edema,” a buildup of fluid in the lungs.

Investigators in Belize say the three women from Massachusetts who died while on vacation had a build-up of fluids in their lungs. The three women from Revere, 23-year-old Kaoutar Naqqad, 24-year-old Imane Mallah, and 26-year-old Wafae El-Arar, were found unconscious in their hotel room at the Royal Kahal Beach Resort last week.
