Continuity mistake: When Chucky kills the coroner there is a generous amount of blood splashing on the gravestone. But in the next shot we can see that he is standing next to the gravestone. Chucky shot the coroner in the back of the head since he was looking in the other direction and is falling on his face, so there should be no blood on the gravestone.
