An individual suspected of being part of the group of Saudis involved in the death of journalist Jamal Khashoggi was reportedly seen around Istanbul wearing Khashoggi's clothes, a fake beard and glasses on the day of the killing.

CNN, citing a senior Turkish official, reported that the man in the video, identified as Mustafa al-Madani, was captured by surveillance cameras leaving the Saudi Consulate in Istanbul on the day Khashoggi died there. He appears to be wearing the same clothes Khashoggi was seen wearing when he entered the consulate.

Turkish investigators have said they have audio and other evidence that proves Khashoggi was killed and dismembered by a group of Saudis in the consulate. The Turkish official told CNN that al-Madani was used as a body double in the operations.

"You don't need a body double for a rendition or an interrogation," the official said. "Our assessment has not changed since October 6. This was a premeditated murder and the body was moved out of the consulate."

Khashoggi was last seen entering the consulate on Oct. 2.

Saudi officials announced Friday that Khashoggi was killed in a “fight” gone awry at the consulate and that 18 people had been detained in connection to the incident.

The explanation promptly drew skepticism from U.S. senators and Khashoggi’s former colleagues, who said the idea of the 59-year-old getting into a fight with Saudi security officials was not credible.

Trump called the explanation a "good first step," but on Saturday acknowledged to The Washington Post that the Saudi comments about Khashoggi’s disappearance were constantly changing.

Saudi leadership initially said they did not know what happened to Khashoggi.

Turkish President Recep Tayyip Erdoğan said Sunday that he will announce the findings of his country's investigation into what happened to Khashoggi on Tuesday.
