A parade intended to show unity and support for the city's rebuilding was instead marred by violence Sunday when shots rang out, wounding three people as the event drew to a close. Not long after the parade wrapped up, police officers patrolling the route heard gunfire. They then found a 34-year-old man with multiple wounds, police spokesman Gary Flot said. Minutes later, after more shots rang out, officers discovered an 18- year-old woman wounded in the leg. A man, 20, also was shot in the leg, in the same area.
