According to a witness who was present when the shooting occurred, the block party took an unanticipated turn for the worst as she saw blood and bodies on the floor.
The injured varied in age from 5 to 61, according to the spokesperson for Medical City Healthcare, which was treating multiple victims at three trauma centres.
