Roger Pratt was stabbed to death while defending his wife from robbers who stormed their yacht in the Caribbean. Roger, 62, was attacked on board his luxury 41ft-long craft which was moored on the Caribbean island of St Lucia at 11pm on Friday (17/1). Brave Roger tried to fight off three men who raided the £200,000 ‘Magnetic Attraction’ vessel but was beaten and knifed several times before being thrown overboard. His devastated wife Margaret, 60, found his dead body floating in the water a few minutes after the horrific attack. Yesterday (Mon), the last picture of Roger emerged showing him walking next to a horse on the day he died. Margaret posted the idyllic snap on their blog – which she wrote to keep friends back in the UK up-to-date with their around-the-world trip of a lifetime. It also emerged that Roger tackled the thieves despite having several cracked ribs and glass embedded in his foot following an accident on deck weeks earlier.
