Later: The perps were racially identified as Chinese (five of them), white (the 17–year-old), and (apparently) black, as seen in the video:
Raymond Palomino [white] was charged as an adult. Hearings for the other six — including the 15-year-old girl [who reportedly lured the victim into the alley], two 16-year-old boys and three 15-year-old boys — were postponed in Juvenile Court as officials sought a Cantonese translator. Five of the six are Chinese, officials said. Their names were not released.
