So after last night's episode I have my top 3 suspects...
1. Lindsay, lots of religious references in the first two episodes (i.e. Bible passage, St. Agatha medallion, etc.) and she said in episode 1 that she is the daughter of a minister. Her behavior in episode 3 makes me waiver a little on my theory as she seemed to come off playing the game more but maybe that's her strategy to throw off suspicion.
2. Cris, especially after episode three I find her behavior odd and if Lindsay was the top "scorer" the only thing I can think that would be different between her story and Ronnie's is "who is the killer?" so to me then that means either Lindsay is the killer or Cris since each week Lindsay picked Cris as the killer.
3. Melina, her behavior is odd to me. I feel like if the killer is there is sabotage or distract the others from getting information then she is doing a great job at it. She seems to encourage others to head down the wrong path.
I do not think Kam or Geno are the killers. Dana's odd behavior would make her my #4 pick. Guarding the monitors?!? I mean really, either she is next to go or she is a genius distractor of a killer.
