CNN has obtained exclusive images of police surveillance, part of the Turkish government's investigation, which seems to show the man leaving the consulate through the back door, dressed in Khashoggi's clothes, a fake beard and glasses.
The same man was seen in Khashoggi's clothing, according to the Turkish case, in the world-famous Blue Mosque of the city, a few hours after the journalist was last seen alive at the consulate on October 2.
The man in the video, identified by the official as Mustafa al-Madani, was allegedly part of what investigators said was an attack squad, sent to kill the journalist at the Saudi consulate during a scheduled appointment to obtain documents for your next wedding.
"We are determined to discover every stone, we are determined to discover all the facts, and we are determined to punish those responsible for this murder," he said in the interview.
According to the Turkish official, in the apparent cover-up that followed the death of Khashoggi, Madani, 57, who has a height, age and construction similar to those of Khashoggi, 59, was used as a decoy for the journalist.
A senior Turkish official told CNN that the video showed that Madani was brought to Istanbul to act as a double corps.
"You do not need a body double for a surrender or an interrogation," the official said. "Our assessment has not changed since October 6. This was a premeditated murder and the body was removed from the consulate."
A Saudi source did not confirm or deny that Madani was sent to act as a double corps, although he emphasized that the killing of Khashoggi was not intentional.
Madani, a decade older than the other members of the 15-man team, left the consulate building by the back door along with an alleged accomplice. Madani was wearing what the video seems to show as Khashogli's dark jacket, gray shirt open at the neck and pants.
Four hours earlier, Madani had entered the consulate through the front door, next to a supposed accomplice. Saudi forensic medicine chief Salah al-Tubaiqi, another key suspect who was identified by facial recognition analysis along with CNN's chronology of events that day, was also present. The video seems to show Madani without a beard, with a blue and white plaid shirt and dark blue pants. When he left the consulate dressed as Khashoggi, the video seems to show that he is wearing the same pair of dark sneakers with white soles that arrived for the first time before the journalist's death.
"Khashoggi's clothes were probably still hot when Madani put them on," the senior Turkish official told CNN.
A consulate guard told the journalist's girlfriend, Hatice Cengiz, who was waiting outside the consulate's main entrance and raised the alarm when he did not return, to CNN, who could have left the building through the back door, he said. friend of Khashoggi, Turan Kislakci.
This surveillance video is another piece of evidence in the mysterious case of what happened to Khashoggi after he entered the consulate almost three weeks ago. It is part of the broader investigation carried out by Turkish officials on the events of that day and the interrogation and international questioning of Saudi Arabia's version of how the journalist died.
Turkish officials have been leaking to journalists a lot of details of the investigation, but have not yet released a key audio recording that, according to sources, exists from inside the Saudi consulate. Turkey has not publicly admitted the existence of the audio.
Below are the movements and actions of Madani and his accomplice, according to the video images obtained by CNN and a senior Turkish official, the day Khashoggi was killed:
