There are lots of stories like this and there's basically never an explanation of why. Apparently some medical examiners and funeral home owners and such are really fucking sick.
There was a university not too far from my town where I grew up that had a mortuary school.
I'm not going to say that all people who become morticians are like this, but there was definitely a type amongst my peers who opted for that career path and they weren't people you would say, "they went to mortuary school? I never would have expected that" about.
The read more button doesn't work for me but since they were removed during autopsy I guess they just got put into a container after being processed but not listed with the bits to be forwarded to the funeral home.
The article says bin but I don't think they're talking about a trash bin, probably a lidded plastic container in the correct storage area.
