(CNN)A little over a week ago, a prominent Saudi journalist walked into the consulate general in Istanbul, intending to get paperwork that would allow him to marry his Turkish fiancée. She hasn’t seen him since.
Since then, officials and journalists have scrambled to piece together the story of what happened to Jamal Khashoggi, a former Saudi royal insider who became a critic of the regime of Crown Prince Mohammed bin Salman.
Turkish authorities have privately said they believe Khashoggi was killed inside the consulate, a startling allegation that is firmly denied by the Saudis. Closed-circuit television footage, flight trackers, intercepted communications and even a bone saw have served as pieces of a puzzle that has spurred a diplomatic outcry.
