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. Spatters 20-21 may have been in the area where Anthony re-entered the Chas's truck through the driver's door. These spatters may be blood dropping from the door's threshold.
