For example, a body lay in a house for a month before people called the police because of the smell, or a shooting in a motel, etc.
They just figured they could go in, put stuff in plastic bags and throw it in the dumpsters, which worked until they had a mattress that had a dead person laying on it until the body had become quite decomposed. They couldn't throw it into the dumpster, it was too big, and then they began finding out about all the rules, regulations, bunny suits, respirators, etc.
I had to just look it up...it was called "Sunshine Cleaning" (now, there's a euphemism...)
Only watched it because it was filmed in Albuquerque, always fun to see familiar sights.
