The video next shows the knife coming near the officer, hitting the side of a train and ricocheting to the platform, where it came to rest. The officer then fired his gun, the video indicates. Rainey said three shell casings were recovered on the station platform and indicate that the officer fired three shots. He said the preliminary indication is that Hill was struck by all three shots, but he cautioned that the investigations have not been completed and there has not yet been an official determination of how many shots were fired and how many times Hill was hit. The knife that Hill allegedly threw at the officers was 8 inches long, including a 4-inch blade, Rainey said. A second knife of the same size was also found on the platform and investigators believe Hill was armed with that knife as well, Rainey said. He showed photographs of both knives to reporters.
