Jacky Sutton was found dead inside a bathroom at Istanbul's Atatürk International Airport. The former BBC journalist was employed as the director for Iraq's Institute of War and Peace Reporting (IWPR).

Fifty-year-old Sutton's cause of death is still uncertain, but the local media has been reporting that she was in tears after missing a connecting flight to Irbil in northern Iraq and committed suicide because of it.

Sutton's colleagues find the idea of her killing herself very unlikely, according to the Guardian.

"I just find it so weird. IWPR had just got a big grant for its Iraq projects and she seemed excited to [get] started," said an unnamed former colleague, according to the Telegraph UK.

And jihadism researcher Charlie Winter told the Telegraph: "We've been in email contact for a while because she was interested in the work I was doing on IS propaganda, so we met face to face last week to talk. We spoke a lot about Iraq and she talked about the lack of meaningful change in the country — how the political establishment is not really adapting or evolving as it should."

"It fundamentally doesn't make sense to me that she is alleged to have killed herself — she was so motivated and driven. It just doesn't add up," added Winter.

Anthony Borden, director for IWPR, said he wants an "in-depth, detailed, forensic investigation" into her death, according to the BBC.
