If the garage door opened and closed within minutes of 9PM, that means someone could have gotten into her house via the interior garage door before Nancy was dropped off. I don't know the timing of the garage door openings and closings, though. Opened and closed once, twice, what times? With the remote, or by releasing the drive and opening it by hand? Does opening it by hand log anywhere? So say someone got in at 9 PM, then took Nancy out at 2:30 ish AM but opened the garage by releasing the drive and it didn't log anywhere? Just my thoughts.
