Avery property and burn-pit photographs, including photo stacks identified as roll four, D-16, D-14, and D-15

During Day 20 cross-examination, Fairgrieve recognized a series identified as roll four, recalled some photographs in D-14, and recalled the D-15 photographs shown to him. He also recalled a photograph of the pit under a blue tarp but could not say with certainty that he had seen every photograph in the sets discussed.
