A Saudi prince will take care of it.
Sadly, I think you’re right. They wait for the media coverage to subside, then someone from Saudi Arabia with a large bank account steps forward and quietly makes arrangements to have the body flown back to relatives. The announcement is usually made after the corpse has left the country.
Hoping that someone in the medical examiner’s office will leak the departure time when the Wahhabists try to claim the remains of their terrorist. I can see the hearse getting pelted with shoes and bacon all the way to the airport.
