As news of these deaths continues to populate headlines, The Hard Rock Hotel & Casino Punta Cana issued its own public statement after two Americans staying at the resort also fell ill and died suddenly within the previous year.
Hotel officials told Fox News they are "deeply saddened by these two unfortunate incidents, and we extend our sincerest sympathy to the families of Mr. Harrison and Mr. Wallace".
The Maryland woman said she continues to be suspicious, especially following the deaths of several more people since.
"He was fine. He and his wife arrived there at around midnight on April 10". The 67-year-old, who owned a construction business, had reportedly taken a scotch from the room's minibar before he became nauseous. "He started feeling very sick, he had blood in his urine and stool right afterward".
The Dominican Republic's authorities said that a preliminary autopsy have found the couple had suffered from pulmonary edema and respiratory failure, caused due to excess fluid in lungs. "We found a lot of medicine used to treat that illness and according to the medical history the family provided, both of them had high blood pressure", the country's national police said in a statement. 'We don't want this to happen to anyone else'.
But despite her wishes, it has.
Arnold said the family has been particularly concerned after having recently learned of the other seemingly mysterious deaths in the Dominican Republic.
News of the deaths has drawn attention to earlier deaths of American tourists at island resorts that received no publicity at the time - some now suspect - may have been part of a pattern.
Yvette Monique, 51, died in June 2018 of a reported heart attack, according to her death certificate, at the Bahia Principe resort, which is the same resort complex that Schaup-Werner, Holmes and Day had died, Fox 29 reports.
Five days later, Maryland couple Edward Nathaniel Holmes, 63 and Cynthia Day, 49, were found unresponsive in their hotel room at the same resort.
Bahia Principe Hotels & Resorts said it followed all security protocols.
Schaupp-Werner died all real away in her resort room after having a drink from the in-room mini-bar, a family spokesperson, Jay McDonald, said in an announcement to ABC News.
The Dominican Republic Tourism Ministry said it extended condolences to the families and friends of those affected in the tragic events that were reported in the country.
"We didn't find out until the next morning that he had passed, which is another weird thing", Tickenhoff, Wallace's son-in-law, told FOX40.
The resort company, Bahia Principe Hotels & Resorts, tweeted out a statement with comments on all three deaths.

Last year, two other American tourists died under similar circumstances at the same resort.
"I no longer feel like my husband died of natural causes", said his widow, Dawn McCoy, according to The Post.
