Stolen from TWOP

The show's writers have already started planning for the show's fifth volume, which will involve a series of mysterious deaths. Or could they be murders?
I'm going to randomly guess some of the murders. Maya, The Haitian, Monica, Micah, Nana, Ando, Hiro, Kimiko, Mohinder, Molly, Rachel, Janice, Heidi, Debbie, Sandra
