Seems like a reasonable list.
What's the difference between a cleaner and the guy that digs/covers holes?
I'm assuming you mean that the first is a profession and the second is a part time thing because you haven't the brains / guts to say no and you are usually just a hanger on?
A "cleaner" is a person who bleeds out and dismembers bodies, mops up blood and wipes down the area with acetone to counter the Fluorescein, packages everything on lime and makes the murder scene look nice and spiffy. It is a skill, but the guys who do this are not respected, they are looked upon as a necessary evil.
Holes, contrary to the movies and TV, in a pre planned hit, are dug in advance of the hit, and cleaners don't generally take the body to the hole, it is usually a separate function
