Don't most heart attacks happen on the toilet? The force of straining and all of that. I think I recall reading that somewhere. Without further evidence, I'd assume dude went up to the third floor bathroom, locked himself in, heart attack / aneurysm while in the middle of using the restroom. Took a few days for the hospital to locate him since he probably went to a seldom-used bathroom.
The only take-away I have for this is to "make sure you get your fiber".
Aah, well. It sucks.
That may be why they have code buttons in the bathroom at hospitals.
Every hospital bathroom I've been in all have a pull string over the toilet. Something goes fucky, you can pull the string and the calvary is on it's way. Public restrooms, that's not the case. Probably not the case in employee bathrooms (but that's an assumption).
I've read this as well...
