Never mind 
It's probably you, Zach and one other name anyway

If I was investigated on day 1, then the BG was most probably investigated on day 2. And since it was between Fred and Zach on day 1 and Zach was saved by the coin toss, it's logical that the D investigated Zach, who turned out to be the BG. On day 3 the Gs thought that Zach and the D were in contact and Zach will protect the D, so they went after him.
So, perhaps....
Day 1: The D investigates me (that's why he never contacted me?), Zach the BG protects me (my hero

Day 2: Gs think only Janna could be stupid to protect me (smells like something X would think) and they whack her. The D finds it fishy that Zach was saved by Kyle's late vote for Fred and he investigates Zach. He turns out to be the BG.
Day 3: The D tells Zach he knows that he's the BG and proves it by telling him that I'm a normal C. Gs assume this and think if Zach will protect the D. They take the risk and go after Zach
Who was investigated on day 3?
I could be way off, but this is the most logical scenario.
