WWOTD? ( Possible Alien Abduction or murder)

What would the OT do? Yesterday when I left in the morning I noticed my neighbors door was open. When I returned at noon it was still open. Wife and I went out to eat last night and when we return the door was still open and no lights were on. It's not uncommon for people to leave their doors open as some of the homes have external laundry rooms. So this morning before church I noticed the door was still open and when returned it was still open. At 2:00 my wife walked across the street an knocked. After 5 mins she went inside. All the furniture and belongings were still there. There were two bed room doors shut and she did not enter them. She came out and shut the door. I think we should call brpd and she just thinks they forgot to close it when the left for a trip.
