Well, I have one final update for those who might be interested. The police did drop by today and looked around the property. They agreed that it was a weird situation but there wasn't enough to enter the property (which was why I didn't contact them in the first place). And, as evidence, I will post a picture although the naysayers will say I probably found it on the internet or something.
Anyways, as if on cue, about an hour later THE HOMEOWNERS SHOWED UP in a taxi, but with no luggage. Maybe it got delayed. I called the police non-emergency number to let them know they were back and the lady that answered the phone said that yes, they had found their daughter who told them they should be returning today.
So, all is well.
