Jacqueline Anne Sutton, known as Jacky, was found in a toilet at Istanbul's Ataturk Airport on Saturday night after flying from London.

Family and colleagues initially expressed doubt over reports that the 50-year-old had killed herself after missing a connecting flight to Iraq and admitting she did not have enough money to pay for another ticket.
