COD Elite: Does the heat map show where those have died, or where those have gotten kills from?

Question

Here's a screenshot of the heat map for a match on Call of Duty Elite:

Now, I can't figure out if the heat markers represent where someone was killed, as opposed to where the kill shots originated. Which is it?

Answer 1

They show the places where others have died.

I tested this out with a friend. I played a match, got a kill on him and left the game. I checked the map and it showed the place he died at with heat.
