Displaying Variable Hash Based on JSON File?

[MyNameIsJeff]

I'm relatively new to JavaScript coming from PHP/HTML/CSS development (mostly websites) so I'm still on the path to figuring out some of the functions JavaScript offers. So far I've gotten a good head start thanks to a lot of you helpful content creators posting scripts and helping me break them down.

I am now trying to get a player killed script going where I want the logs to show the killer, dead player, and the reason.
I've got the code down, however, I can't figure out how to collect data from a JSON file and convert it into a variable which can be used in the playerDeathHandler function...

Trying to use this as the database for reasons:

Can anyone spare any insight on this? Much appreciated!
