Sattahip police said a Canadian man found dead on his yacht died of a heart attack.
The body of Gilbert Tourville, 61, was found Nov. 23 by a friend around 2 a.m. He had been dead about eight hours.
Friend Denis Bachand said Tourville had canceled plans to go out for Loy Krathong, complaining of chest pains. Bachard went out for the holiday, but returned to the boat to check on his pal.
