Retired British couple found dead during Caribbean beach vacation

A retired British couple were mysteriously found dead on a beach in the Caribbean on Saturday and local reports indicate that they may have drowned after the husband got into difficulty in the water and his wife tried to save him.

David Foster, 76, and Rosaline Foster, 77, were found dead on L'Esterre Paradise Beach on the island of Carriacou, the Royal Grenada Police Force said in a statement. Carriacou, a seven-mile-long island, is part of the Grenadine Islands and is known for its crystal-clear waters, sandy beaches and pristine coral reefs. 

Police say they found David Foster lying on the sand, and say he was pronounced dead at the scene by a medical doctor.

David Foster may have suffered a heart attack while in the sea and his wife went in to help him, only to get into difficulty herself, Cpl. Ardell Lewis told the BBC.

"The basic facts seem to suggest the man may have suffered a heart attack and the lady may have gone to his assistance, and she probably would have drowned," Lewis said.

An autopsy is being conducted to determine the cause of death and police say an investigation is ongoing.

Their deaths bring the number of tourists who have died in Grenada so far this year to four, according to media outlet the Loop.

Last month, police say a Virginia couple were attacked and killed by a group of escaped prisoners who boarded their catamaran yacht before tossing the victims overboard. 

Ralph Hendry and Kathy Brandel had reportedly sold their possessions to buy and live on their yacht, called "Simplicity," which was reportedly left in tatters and covered in blood. Three men have been charged with murder, among other charges.

Meanwhile, earlier this week, a woman on a cruise liner bound for the Bahamas was found dead in her cabin and police say they later found cocaine in her living quarters.
