ive had a couple investigators from other agencies say it may be dust. however when i tell them we have 3 pictures on either side, as i was told to do....set the camera to burst and take multiple pictures at once. the 4th of 7 was the only picture to come up with this and the others have no dust orbs or anything to make it questionable. the other side is the park where this was taken has several deaths associated with it, including 2 small boys
