Explain why an autopsy is performed even when a death is not suspicious.

An autopsy is performed even when the death isn't suspicious, becasue the want to make sure that the person did actually die from natural causes, or however they died. People could make it look like they died a certain way, but they could have actually been murdered. 
Do you get what I am saying?
Hope this helped! 

an autopsy is performed even when a death is not suspicious,because they still need to find out the cause of death and make sure everything looks legit to how they died.
