The U.S. Department of State confirmed to ABC News that they are "actively monitoring" the investigations into Miranda Schaup-Werner's death and those of Edward Nathaniel Holmes and Cynthia Ann Day - but "At this point, we are not aware of any connection between these incidents", an official said in a statement.
She enjoyed a drink from the hotel minibar and then shortly thereafter suddenly collapsed in her hotel room, family spokesman Jay McDonald told WFMZ-TV 69. However, high blood pressure meds were found in the room, but that's not out of the norm given Holmes' age.
A vacationing Pennsylvania psychotherapist died at the same hotel where two USA tourists were found dead five days later, according to Dominican authorities, who said Wednesday they are investigating the causes of the deaths.
Werner attempted CPR and called for help, and responding paramedics administered an epinephrine injection, typically used to treat life-threatening allergic reactions, but Schaup-Werner was declared dead soon after.
Days before their deaths, Holmes posted Facebook photos of the couple enjoying their time in open waters. The couple was checking out five days later when they were found.
"Boat ride of a lifetime!" one caption said. Cynthia Day and Nathaniel Holmes checked into the hotel the same day as the Werner's, and were set to leave on May 30th. "We are deeply saddened by this situation and express our deepest condolences to the family and friends of the deceased". They were found unresponsive by hotel staff after they missed their scheduled check-out time on Thursday, according to a statement from the hotel. The couple's bodies have been transported to the Dominican National Institute of Forensic Sciences for an exam.
Back in March, authorities discovered the bodies of Orlando Moore, 43, and his girlfriend, Portia Ravenelle, 51, at the bottom of a cliff.
Moore's sister, Lashay Turner alerted the U.S. Embassy in the Dominican Republic and subsequently filed a police report. She was rushed to the Doctor Dario Contreras Hospital in critical condition and died on April 4.
