Knoxville??
The one city in the USA with a Body Garden??
Yea The University Of Tennessee has it. Forest Hills the neighborhood this happened in is a quiet neighborhood. This seems to be a woman and a special needs son. Forest Hills BLVD used to be a through road that crossed the interstate and came out on Papermill Rd. Interstate upgrades over the past decade or two lead to the tearing down of the interstate overpass and it is now a dead end road. But it is also close to Kingston Pike in the Bearden area where homeless frequent.
It's mainly a wooded neighborhood and at night yea a homeless person could sneak up and find a place to hide. The deck by the pictures seems to be her back yard with a steep bank going down hill behind her house.
