Robert Wallace of Turlock, Calif., arrived at the Hard Rock Hotel & Casino resort in Punta Cana with his wife on April 10 to attend his stepson's wedding but fell ill nearly immediately the day after.

Maryland woman Dawn McCoy reported that her husband, David Harrison, died in similar circumstances almost a year ago at the same Hard Rock Cafe Wallace, according to Fox News. "He deserved better", she added of her son. He had a physical shortly before the trip and, with the exception of high blood pressure, which he kept in check with medication, he had a clean bill of health. Unfortunately, Harrison did not make it.

The FBI and the U.S. Centers for Disease Control and Prevention (CDC) has confirmed that they are probing the mysterious deaths at resorts in the country.
