Denise Wolff was gunned down in front of her home in a quiet South St. Louis neighborhood. Police thought they had the killer until their star witness wrecked the case.
They have run away from home or been kicked out, and there are about 5,500 of them in the St. Louis area. They're homeless teens -- too old for foster care, too young to live on their own.
