makes it difficult to find

As I walked in the woods, I found a disturbing array of things, which might lead someone to believe "evidence". Whereas it is general debris and trash, if it were a crime scene, finding hard evidence would be really difficult.
web of lies
shot glass with writing
knife
For what purposes was it used?
Natural or useful material?
Inside a log there are pieces:
glove, bottle, wrapper (below shown removed two jackets. One jacket had a piece of gum in the pocket)
Two jackets of different thicknesses, still spring or Fall jackets
You can see a broken top of bottle ... of value?
How old is the bottle and is it relevant to your search?
The mattress has been there for a while, but it is important to the scene?
What could be waste might be old material for binding.
Unconventional for binding, but painting tape is here.
Thick rope left on the ground, was it junk?
This part of a shoe, goes to whom?
This firepit on public property ... to burn something specific?
Was this box from someone involved?
You can read the lettering, but do you know the bottle?
There is a scrap of plastic with print.
There is a rusted bar nearby.
There's an old table-mounting chair for infants/toddlers.
There is a perhaps traceable coffee lid.
It's time to add things up and come up with what you have.
Is it scrap from a bong party?
Was it material left from hillbillies or the like using public property as their own?
Was there a crime?
