OK, let's assume for discussion's sake that Audrey was having a smoke in her garage and was killed by an intruder who had been hiding in the bushes waiting for the garage door to open and for her to sit down peacefully with her smokes.
So, the killer(s) enters the garage. Puts foot coverings on (because we know from PK that there was no blood on the garage floor). Stabs her 12 times with a knife. Adds other injuries. Kills her. Then, the killer(s) have to take the foot coverings off, hop skip and jump around the dead body, run to the indoor garage clicker in order to close the garage door, and then quickly duck down and make their escape before they get crushed by the descending garage door.
Does that make any sense? How else would the gargage door be closed?
