In a wrongful death case, the main thing the jury will want to know is what caused the death of the person. A pathologist is usually called to provide this information. A pathologist is an expert doctor who specializes in understanding the cause of death of a person. The pathologist will perform an autopsy, which is a clinical examination of the individual’s body. When the autopsy is undertaken and done, the main purpose would be to evaluate and find out why the person died.
