Bostani's alleged role in the murder of the Saudi journalist are unclear, as are details of the traffic accident in Riyadh - prompting accusations of a cover up by those who orchestrated the Khashoggi hit. Meanwhile, a columnist for Turkey's Daily Hürriyet wrote on Thursday that Mohammad al Otaibi, Saudi Arabia's Istanbul consul-general, would be "the next execution."

Turkish daily Yeni Şafak reported Oct. 17 that Al-Otaibi’s voice could be heard in one of the recordings, which Turkish authorities are believed to have, of Khashoggi’s “interrogation” at the consulate.

According to the report, after Al-Otaibi told the interrogators to “do it somewhere else outside or I will be in trouble,” he was told to “shut up if you want to live when you are back in Saudi Arabia.”

Al-Otaibi returned to Saudi Arabia on Oct. 16 before his residence in Istanbul was searched by police for more than eight hours on Oct. 17 and Oct. 18. -Daily Hürriyet

Another suspect's photograph was released from security footage on October 18 by the newspaper Sabah, which reports that 47-year-old intelligence officer Maher Abdulaziz M. Mutreb, who previously served at Saudi Arabia's London embassy, "landed in Istanbul at 3:38 a.m. on Oct. 2 and went to his country’s Istanbul consulate at 9:55 a.m.," according to Hürriyet. 

Hours after Khashoggi’s arrival and disappearance, Mutreb left the consulate and visited the consul’s residence at 4:53 p.m., left his hotel at 5:15 p.m. and arrived at the Atatürk Airport for his return trip on a private jet at 5:58 p.m. -Daily Hürriyet

Mutreb had travelled extensively with the crown prince, perhaps as a bodyguard according to an October 16 report in the New York Times. 

Khashoggi, a US resident and Washington Post columnist who was critical of the Saudi government, reportedly took seven minutes to die adccording to the Middle East Eye and the Wall Street Journal. 

In perhaps the most gruesome details from the report, MEM reported that Dr. Salah Muhammad al-Tubaigy, who was identified by the Times and other media outlets as an "autopsy expert" whose presence cuts against Saudis' suggestions that the killing wasn't premeditated, started cutting Khashoggi's body into pieces while the journalist was unconscious, but still breathing. Previously, Khashoggi had been knocked unconscious after being injected with a mysterious substance.

Later, the NYT reported that the hit squad cut off Khashoggi's fingers while he was still conscious during an interrogation where he was also beaten and tortured before being dragged into another room where they finished butchering him.

According to WSJ, voices on the tapes can be heard asking the Saudi consul to leave his office before the hit squad murdered Khashoggi. The consul, al-Otaibi, departed Turkey for Riyadh Tuesday afternoon after the Saudis, in a sudden reversal, denied Turkey's requests to search Otaibi's residence, saying his home was off limits to investigators.
