Just some things I noticed…
pic #1 - looks like some kind of ac unit in the wall. This place has been around for some time, not just 6 mo's.
pic #2 - there are boxes under the pile of dirt. What's in those boxes?? Were they attempting to bury some kind of evidence??
pic #3 - These are men's clothing and I think shoes/slippers.
pic #4 & 5 - what in the world is that hanging on the wall???
You guys already pointed out the child's high chair.
