Yep, I saw a special on A&E or Discovery about a guy who runs a company that "cleans up" after crime scenes and deaths.
They had one instance where an old lady who lived alone died in her house of natural causes and they didn't discover the body until several days later (in the Summer in New Orleans w/o AC to boot) and they had to go in remove the remains and clean the house. Icky.
I saw a similar show where they cleaned up after all kinds of crime scenes and hotel depravity. I think it was Las Vegas or Los Angeles. Icky is only a start at describing it
