Richard Chaput, 64, from Libertyville, Illinois, was snorkeling with two friends Wednesday afternoon, while his wife stayed on the beach. At around 2.15 p.m., Mr. Chaput seemed to be having some difficulty and he and his friends started to return to shore.
En route back to the beach, police said Mr. Chaput apparently lost consciousness. His friends shouted for help and several people who were on the beach came into the water to assist, police said. He was brought ashore where members of the public and two fire officers from the West Bay station administered CPR until the arrival of the paramedics.
Mr. Chaput was pronounced dead on arrival at the Cayman Islands Hospital.
Police said there appeared to be no suspicious circumstances surrounding the death.
