If he traveled...I can see those services being cut off. But he could want to keep the apartment. What I don't understand is how his car set out in the parking lot with expired tags and the management didn't get suspicious. Or have the car towed.
@berdie @Gefn If he had an assigned parking place and car was there, no one would have questioned it. Owners of apartment complex would not have checked car plates; they were getting paid so why look at his car? Car would not have been on the road for cops to see expired plates.
When I lived alone, I had two parking spaces in front of townhouse that were mine. I owned/own the place, so no mortgage, utilities automatically paid. I did not go to the solid metal front door after dark if the door bell rang or there was a knock.
The other thing is, mostly seniors live there. Owners have to know the gate code numbers to get into the small complex of houses. One night there was a knock at my door. I didn't go to door. A bit later, I got a phone call. It was a couple who live across from me. They had not seen me for several days, so the wife had come across to my house to see if I was okay. That is how it is there - seniors look after seniors. I was the senior medical person if someone had medical trouble since I was an EMT.
@Gefn, how is it where you live in your new place? Do you have assigned parking, do people get to know each other so someone might check on you if you were not around for a couple or more days?
