"If the entry point was through the open garage door, it implies that either" the really scary thing about this scenerio [which includes knowing that the alarm system would also be turned off, and even the garage would be left open after the family came home, remember ed pushing the garage door button and the door not closing, and ed just leaving it open.] is that ed is the only person that knew these details besides the person who entered the house that night.
