Three other victims brought themselves to the hospital.One hospital received 11 of the victims for treatment while another person was transported to a different hospital. One person went to an urgent care facility with multiple gunshot wounds, Chacon said.Police have a very general description of the suspect and the incident appears to be isolated to the area, but could not say for certain that there was no additional public danger because the suspect is not in custody, Chacon said.Police are currently reviewing camera footage from multiple sources, including the Public Safety Camera System, police body cameras and business surveillance video to determine what happened.Detectives from the Aggravated Assault, Homicide, Organized Crime and Gang units are involved in the investigation, police said. Investigators have not ruled out gang involvement, but say the motive and circumstances that led to the shooting are not clear at this time.The FBI Joint Terrorism Task Force Team is also on scene, Chacon said.Shortly after the shooting, the Austin Police Department had urged in a post on Twitter for people to stay away from the 6th Street downtown area.
