Okay, even if the man who killed the private investigator, it must be someone from the list. At the scene she answers the door, we can see the killer's shadow and we can see he has hair so we can eliminate Brett and Gale. When Cho asked, she said the man who she was working for was from visualize so my guess is Haffner. I'm not saying he's RJ, I still think this is a fake list. I think PJ is working alone, he can't trust anyone
