A recent post at AskReddit said, "Autopsy Doctors of Reddit, what was strangest discovery you’ve made while preforming an autopsy?" (sic) Responses came in from medical examiners, autopsy techs, EMTs, pathologists, embalmers, med students, and plenty of other folks who have seen. Some. Stuff. Here is one example.
6. "When I was in my intro to EMS class, my teacher brought in a death investigator and former autopsy examiner to speak to our class. She told us while she worked as an autopsy examiner, she got this woman who, at the time, mysteriously suffocated after a car accident. Apparently, while she was driving, she grabbed her lighter from her purse and was holding it in her mouth while she fumbled through her bag for her cigarettes. While doing this, she got T-boned."
"The airbag went off and on the way to the hospital, they kept trying to put tubes down her throat to open her airway cause she was having trouble breathing. But no luck. She said when they cut open her throat during the autopsy they found her lighter jammed down there. Apparently, when the airbag went off, it got jammed down her throat and no one knew."
