Spatters are numbered from east to west and south to north. The number generally indicates Anthony's progression. Early spatters show passive flow of blood, indicative of less serious wounds. Spatters (11-13) show higher velocity spatters, indicative of a breach of the heart. Note the spattering on the curbing. It is in the area of spatters 12 and 13 that Chas Schwartz saw Anthony and Brad fall to the ground.
