This is something that I've always thought about but have never sat down and figured out properly: who killed who in each of the films? Potential spoilers...

Spoiler:

Obviously in the 3rd one it was just the one killer so we know he killed everyone, but in the other films there were two killers - so who committed what? Charlie killed Olivia because Jill was watching it happen with Kirby from the next house, but what about the rest of the murders when we didn't know who the killers were? And then what about the first two films? It's always something that I've thought about but never tried to work out, just interesting to imagine the logistics of two murderers working in tandem switching between roles in the films.
