A Maryland woman said that three American tourists dying at a Dominican Republic resort has her questioning the circumstances of her husband’s death in that country.

Dawn McCoy said she does not believe it’s a coincidence that her husband died in 2018 of pulmonary edema and a heart attack — much like the three Grand Bahía Príncipe resort guests who died within a week of each other, news station WTOP reported.

“I started seeing all these other people that were dying of the same exact causes, which made me start to second guess,” McCoy told the news station.

For her wedding anniversary, she visited the Hard Rock Hotel and Casino in Punta Cana last July along with her husband, David Harrison, and son.

She said her husband started feeling sick one night before he went to bed. He later woke up in the middle of the night covered in sweat.

“He couldn’t sit up, and he was making noises that you couldn’t make out,” McCoy said.

She said she tried to talk to him “but all he could do was mumble.”

“He was struggling quite a bit to get out of bed and to talk,” she said.

McCoy called the hotel doctor to the room but her husband didn’t survive.

“We went down there as a happy family, and we came home a broken family,” McCoy told WTOP. “I came home a widow and my 12-year-old son came home fatherless.”

She said her husband was prescribed medication for high blood pressure — but had received a clean bill of health from his doctor before the vacation.

Dominican authorities ruled his death was the result of pulmonary edema and a heart attack.

When reports surfaced of the recent tourist deaths, McCoy said she began to question the circumstances surrounding her husband’s death.

“I no longer feel like my husband died of natural causes,” McCoy said.

Miranda Schaup-Werner, 41, of Pennsylvania, visited a Dominican resort and succumbed to a heart attack on May 25 in her room, according to a preliminary autopsy.

Her brother-in-law told Fox News she also suffered from pulmonary edema and respiratory failure.

Nathaniel Holmes, 63, and Cynthia Ann Day, 49, were found dead five days later in their hotel room at the same resort. The engaged Maryland couple’s cause of death was also listed as pulmonary edema and respiratory failure.

Dominican authorities reportedly discovered blood pressure medication, as well as three prescription bottles, in the couple’s hotel room.
