The son of a retired British couple away on a ‘dream winter escape’ today demanded the truth about their suspicious deaths in Thailand, described by Thai authorities as ‘coincidental’.

George and Eileen Everitt were among the victims of five mystery deaths in the northern Thai capital of Chiang Mai and now their son Stephen Everitt says he is suspicious of a ‘cover-up’.

“How could they die of heart attacks at the same time. My parents were fit. My father was an electrician and when he took a massive shock at work doctors were amazed at the strength of his heart,” said Stephen Everitt, 48, today.
