Mongo Think about it, Kira cannot force another person to murder another, and the fact that nomad was dismembered and the use of chloroform can still me smelled, means it was likely a kira supporter killed Nomad, The Reason being, I have no idea, as he did say spilling blood is needed for the new world, which makes him an odd target by a kira supporter.
However, What if he attempted to kill gunfanic? Kira cannot be killed by normal means, and it was shown he could wind up dead upon attacking kira by a supporter? This could actually point more in the direction of gunfanic since I did too believe he was a kira supporter.
So Case in Point, I think we have strong evidence pointing at Gunfanic.
Quick Edit: In thinking more about it, It does make sense that yes Nomad was heading to Canada to kill kira, Which I believe to believe to be Gunfanic, and thus he was stopped in Michigan by an angry kira supporter and was killed. I say we have enough information to lock him up, But if L can hear me, I want us to wait for the 5th Kill, that being said, the reason why is hopefully L Can lock up snake91 or Heartofsorrow. Both of them may have been touched by kira and be the second one. Though there is also a chance that he didnt choose a second kira, this would be by far the safest route.
Ok I can understand you thinking I might be a second Kira because after all I am a civilian and possible Kira supporter but body dismemberment? If it was me I would make it obvious by having nomad's chest open and his heart missing like I said in the "I'm so mean I scare myself" thread. Besides I think you are just adding my name into the mix because I have voiced my suspicions about you.
