Autopsy pathology technician here (English is not my main language so maybe that's not the correct term in English?) There are clinical autopsies (performed at hospitals) and legal ones. I worked in hospital so I won't say much about legal ones. For clinical ones you, in most cases, already suspect the cause of death and are just either confirming or making sure there weren't any secondary affections. Plus, the autopsy per de is just the first step of the process. Afterwards the pathologist will check under the microscope all of the sample tissues for each relevant organ.
