Saudi officials are preparing to say that, after nearly two weeks of denials, prominent Saudi journalist Jamal Khashoggi was killed by mistake during an “interrogation gone wrong.” The changing Saudi narrative over Khashoggi’s disappearance came as Turkish forensic investigators wrapped up their search of Saudi Arabia’s Consulate in Istanbul, nearly two weeks after the prominent journalist and Washington Post columnist entered the building and vanished. Turkish officials have said Khashoggi was tortured and murdered by a squad of 15 Saudi hit men, who dismembered his body. Video filmed outside the consulate Monday showed workers carrying buckets, mops, trash bags and a carton of bleach into the building hours ahead of the arrival of Turkish crime scene investigators, who reported they smelled cleaning chemicals when they arrived on the scene.
