EDITED 4/24/15:
I was planning on making tonight a bit of a simpler challenge, but it seems that some asshole has stolen the immunity necklace. Because I am a lazy challenge coordinator, I decided it'd be a bit easier if I just made you guys figure out who stole the necklace. During the five minutes of actually looking, I DID find a lead. You guys will have to figure it out from there though. Good luck!
Bennett's Lead:
The first location can be found in a group game that is numbered: (my amount of karma)*19
Somewhere within this group game, you will find your next clue.
That's ded true.
