More On The Welfare Crowd

In the last installment, the welfare crowd was breaking into my vacant house, squatting there, and stealing things. I went back there yesterday to fix the hole in my wall that they left when they pulled out the air conditioner and found a new level of insanity had started.
First, they are very cleanly squatters. They always pick up after themselves. There is just enough movement of the items in the house, so that you know someone has been there. They even fold and replace the blankets on the bed they are sleeping in.
The really strange thing, is that items are now reappearing in the house. Not the expensive stuff like the air conditioner or the bicycle, but little things. Specifically, the dog bowls they stole and 3 pieces of firewood. Seriously? Why would anyone return those items?
The freaky part is the fact that when I returned home, my realtor called and told me that someone had put an offer on the house for $22,000. Now, since the house has been on the market for over 2 years and has only had one other offer, and since similar houses in the area are selling for around $70,000, the timing and the amount just seem suspicious.
