How to track eliminated and eliminating player?

I want to track the player who has eliminated another player and be able to track an eliminated player so I can give those two individuals two different effects of the elimination. For example, in a gun game, I want to grant the eliminator the next weapon and possibly downgrade the eliminated player. Still, I am unaware of how exactly to figure out the elimination_result stuff off the digest.

I know several ways I can do this using creative devices that already exist in the game, but I thought it’d be interesting to figure out how to do it through code. And right now, all I could figure out was tracking that an elimination has occurred in the game but I don’t know how to define who did what and do stuff with that information.
