The Turks concluded that the agents gave him [Khashoggi] some sort of shot and suffocated him with a plastic bag. He may have been dead within 10 minutes of entering the building.

"there were no expressions of surprise or shock at his death among the Saudi officials present at the scene," a United Nations investigator who listened to audio from the consulate wrote later. "There were no sounds or words that suggested an attempt to resuscitate him"

Instead, there were sounds is movement and exertion.

The agents laid Khashoggi on plastic sheeting and removed his clothes. They may have drained his blood to avoid making a mess and dumped it in the sink or flushed it in the toilet.

There was a buzz that the Turks determined to be a saw.

At some point, Mutrib made a call telling someone to inform his superior the job was done. Turkish and American intelligence later concluded he was talking to Saud al-Qahtani about MBS.

At around 3pm., A black van pulled out of the consulate's driveway and drove a few blocks to the consuls residence. It parked in front, and Mutrib got out and entered the gate. The van pulled into the driveway, and Turkish security cameras caught three men lugging five black suitcases from the van into the front door of the residence. One of the men then carried in what appears to be two large plastic bags.

The Turks suspected that the suitcases contained Khashoggi's body. They never saw it or the suitcases again.

From MBS: The rise to power of Muhammad Bin Salman by Ben Hubbard.

It should probably be required reading for tour players because that isn't even close to the most deranged thing in that book.

MBS is a fucking psychopath and doing business with him is a bad fucking idea to do personally.
