The man, identified as Loyd Wayne Loudamy of Mansfield, Texas, was with his wife and his best friend on a snorkeling excursion at the Callie dive site in the vicinity of the Royal Watler Terminal, Royal Cayman Islands Police Service officers said.
Officers said Mr. Loudamy and his friend were snorkeling at the site while his wife remained on a boat nearby. Less than 10 minutes into the snorkeling trip, he got into difficulty and he lost consciousness in the water, police said.
Mr. Loudamy was lifted out of the water onto the boat where CPR was administered by two other snorkelers on the same trip. One of the tourists who administered the CPR was a nurse here on vacation. During the administering of the chest compressions and CPR, police said Mr. Loudamy regained consciousness.
The George Town harbour patrol boat was called in to assist with transportation of the victim to the Royal Watler Terminal where paramedics were waiting his arrival. The same two snorkelers continued the chest compressions and CPR while on the Harbour Patrol boat, but Mr. Loudamy lost consciousness again, police said.
He was taken to the Cayman Islands hospital where he died around noon Thursday.
Police said there were no suspicious circumstances surrounding the death.
