Lisa Fernandez of Fox 10 writes that another American tourist has died in the Dominican Republic: The latest casualty is a California man who fell critically ill at an all-inclusive resort about a month before three others died in their rooms, Fox News has learned.

In all, six U.S. tourists have died in recent months while vacationing in the Dominican Republic – a trend that the FBI is now investigating. 

Robert “Bob” Bell Wallace, 67, of Modesto, and who grew up in Redwood City, became sick almost immediately after he had a scotch from the room minibar at the Hard Rock Hotel & Casino resort in Punta Cana in April, his niece, Chloe Arnold, told Fox News on Sunday. He was in the Dominican Republic to attend his stepson’s wedding. He is survived by his wife, Beverly Tickenoff Wallace, according to his obituary. The two had three children between each other. 

Punta Cana is a town at the easternmost tip of the Dominican Republic and touches the Caribbean Sea and the Atlantic Ocean. The spot is known for its beaches and lavish resorts.
