Amy drops like she's been shot, tossing the knife aside as she does so. Amy hears gunshots and closes her eyes. The next thing she hears is the voice of one of the police officers.
Officer: Are you okay, miss?
Amy opens her eyes.
Amy: (confused) Uh...
Officer: Are you hurt?
Amy looks back and sees an another officer standing over the KILLER's dead body. He must have been right behind her when the cops shot him.
Amy: My ankle.
Officer: Okay, don't worry, we'll get it looked it. What's your name, ma'am?
Amy: Amy. Amy White.
Officer: Okay, Amy. You're safe now, the ambulance will be here shortly.
