Who do I think it is, the murderer of these people.

Lombard.

Why?
He's never been sympathetic. He's always been a greedy, bitter man. Compared to being a predator, an evil face and devious smile.

Truthfully at this point I haven't a clue as to why he wants to kill all these people. Maybe for justice, maybe just an evil desire.

Notice how he points at someone and accuses them of being the murderer, and then they die?

He's easily sneaky, hiding around his revolver.

It's just him! I don't know how, I just know...
