Can an autopsy be performed after burial to find if person was smothered to death?

Yes, an autopsy can be performed after burial, a process known as a post-mortem examination. However, it is more challenging due to decomposition and the potential loss of evidence. If there are specific signs or circumstances suggesting smothering, forensic experts may be able to determine the cause of death, but the accuracy may be diminished compared to an autopsy conducted before burial.
