Budi Sampurna, a professor at the University of Indonesia and member of the forensic team responsible for identifying bodies from the crash, said one autopsy had already taken place, but he didn’t comment on the cause of death. He also didn’t say how many other autopsies were planned.
I posted this 3 January. So yes autopsies have been done. I just think they don't want to talk about it because of family sensitivities.
