A Denver man has died after becoming critically ill in the Dominican Republic, KDVR reports.

Khalid Adkins traveled to the Caribbean island with his daughter last week, his family told the station on Wednesday. Adkins was supposed to fly back home on Sunday but reportedly dripped with sweat and vomited in the plane's bathroom, forcing flight attendants to eventually remove him from the flight.

On Tuesday, Adkins's sister-in-law, Marla Strick, told KDVR that, prior to his death, Adkins had been hospitalized in Santo Domingo, the country's capital.

"He said his leg started to swell and that’s why he couldn’t get up. And he started sweating and vomiting. He is just yelling and in pain, so he couldn’t talk to me," she said at the time.

Strick added that family members — including Adkins's own daughter, who had already flown back home — had been having trouble getting any more updates from hospital staff on Adkins's status. They were only told that his breathing was "bad" and that his kidneys were failing.

Earlier this week, a relative attempted to raise enough money — $20,000 to be exact — to fly Adkins back to the U.S. for treatment via air ambulance by creating a GoFundMe account. Though it raised enough, it was too late.

"We found out this morning that he passed away last night!!" an update on the account's page read. "I am at a loss for words we have no explanation of what happened all they will say is he get sick!! We need to get his body home anything helps please!! We really want to know what happened!"

Adkins is the latest American to die in the Dominican Republic. At least 10 deaths have occurred at resorts throughout the island, and many of them have involved the consumption of suspicious alcohol or the use of hotel amenities.

Last Monday, New York resident Vittorio Caruso died after falling sick at the Boca Chica Resort in Santo Domingo. His sister-in-law told Fox News last week that "he was brought by ambulance to the hospital in respiratory distress after drinking something." Dominican officials later determined that Caruso died from respiratory and heart failure.

Other victims include New Yorker Donette Edge Cannon, Pennsylvania woman Yvette Monique Sport, Maryland resident David Harrison, Californian Robert Wallace, Ohio resident Jerry Curran, Pennsylvania resident Miranda Schaup-Werner, Maryland couple Edward Nathaniel Holmes and Cynthia Day, California resident Robert Turlock, New York resident Leyla Cox and New Jersey resident Joseph Allen.

Dominican officials have since attempted to play down concerns over their country's safety and quality of life. In an interview with Fox, Ministry of Public Health spokesman Carlos Suero hit back at critics who have suggested that foul play may be involved.

"People die all over the world," he said. "Unfortunately, very unfortunately for us, these tourists have died here. We had about 14 deaths last year here of U.S. tourists, and no one said a word. Now everyone is making a big deal of these."
