Autopsy report as novel intro? How?

Hey, Tildes! cqns here -
After four-ish years, I've finally sat down and realized that my "novel thing" is...non-conventional at best. As such, it required a whole rewrite of the introduction, beginning with a cold open, an autopsy report. Problem with that is (1) I'm not a medical professional in any capacity and (2) I've already looked up how to do this (Reddit's no help, obviously). Basically, I want this autopsy report to look realistic and to also increase my understanding of how to decipher one so I can get an idea of how to write it...
