All right, I've crunched some numbers, and here's what I've got. There are four players left, and there are three roles, which are:
Killer!
Investigator
Doctor
Now, I'm the last pure townie, so that means the other three players have roles. Dasmos can't possibly be the killer if he never logged on for some of those days like someone else said, so that rules out him. All right, so here's what bothers me. In one of the previous days, Khushrenada stated that he had no role and was a regular townie. Looking at things now, that can't possibly be true. So it just leaves the question, did he lie to protect his townie role, or is he actually the killer?
I'm going to wait until you two post some thoughts before I cast a vote.
