We were taken out into the woods a little bit and was indeed an area with disturbed soil. To me it didn't look like a grave site. It looked more like a rotten stump to me, where the wood had just turned into like humus. There were no plants growing up through it really. So it was a barren spot. So it kind of looked like it was disturbed.
The normal grasses and moss and stuff growing in the area around it weren't here, so it did look odd. There was some whitish colored plastic sticking up out of the ground in sort of a perimeter, maybe 3 feet in diameter. The plastic to me looked like it was decomposing, getting brittle and just flaking off on to the ground, on its own. Those little flakes were still there right under the plastic.

A warrant was then obtained for the burial area, to search that. And then I began the excavate this humus like material, moving it on to a tarp, digging down. I dug down a little ways and the white plastic perimeter was actually underneath all of that humus material on the flip side of the white plastic, was the label peat moss. It was an old bail of peat moss.
