I have no way to prove it, but I would have kept him around for awhile.
When River got hit first, I figured 1) It could have only been a handful of people 2) It could have been random 3) People are gonna think it's me, **** I'm dead...
...and 4) It's Gundy. It's so Gundy. And I have the suspuscion that Gundy wants me around as a patsy. He'll keep me around to use me as a diversion, trying to take the heat off him....and then murder other people (those of fewest consequence) when everyone else is distracted.
Now, seeing as how I may have uncovered his rouse, he'll definitely want to keep me around because by whacking me he would have proven my inquiry. By getting you guys to vote me off next...he looks blameless. Of course, I could be dead wrong and the real killer will whack me just to make everyone else think it's Gundy and continue to hide themselves in the shadows. So if I die next...well, it may not be Gundy.
But then it could be. Maybe he'll do the opposite of what I just said simply because he's crazy enough. Yep, it's totally Gundy.
