“””””I don’t see any brown liquid..””””
On the far right there is appears to be a clear plastic water bottle with the label stripped off...and stained brown from some other liquid.
The brown bottle is identical in shape and height to the bottled water with the blue top and label (not the Deer Park)
Maybe, but as I look at the third picture down it does appear that is residue of a darker liquid, but the bottle does not seem to me to be identical to the other one you mentioned. There is a bulbous area just down the neck with an indentation above the part where the label would be. Also, there is another rounded, protruding area at the bottom. It does look as if part of the label is still on this bottle, too, if you look at the left side of this bottle. The “identical” bottle you mentioned doesn’t seem to have those rounded protrusions, but maybe it would appear to if you took off the label. (Just my observations.)
