Forensic scientists, what is the most WTF case that you ever had?

A friend of mine is a CSI and I don't know if he's posted here, but just in case he hasn't, I'll put this here.

Anchorage, Alaska, 2008.

to the morgue and autopsy at the family's request because no obvious means of death can be found.

to have gotten into her shower, and then her heart stopped due to terror. As far as I know,

When I was pretty young, I got into all of like the procedural crime shows and stuff, like
