Hello person reading this, I want to give you my theory about the murderer.

Lizzie, I think she did it because of a lot of evidence pointing towards her.

  • She took the knife from Carol
  • About an hour later Karen and David were found dead (stabbed and burnt) I think she did this to stop the infection from spreading to the rest of the group
  • Next, she's so sick that she forgets to cough, cough blood or sweat heavily

I think she's going to go into the infected place, kill all the infected people she can (possibly Glenn as well) and finally get caught, after that I don't know what will happen to her.

What do you guys think?
