1010RD :" Or that while shooting he pushed up a pile of rocks/gravel with his foot."

I guess that is why the SEALS and the FBI are investigating the scene, both specialists in firearms and forensics , respectively .
Part of that investigation would include location of shell caseings at the gravel (as a marker),
or six feet forward of the gravel, assumeing that he was lying prone and firing from some distance away.
