CLINTON, Ill. - The rescuers arrived at Clinton Lake that September evening to find a car submerged in the water and a mother screaming from the shoreline, her boyfriend by her side. Investigators said it took only a minute or two to pull three children from the back seat, but it was too late. Six-year-old Christopher Hamm and his half brother, 3-year-old Austin Brown, were pronounced dead at a Clinton hospital a few minutes later. Kyleigh Hamm, 23 months, was flown to a Peoria hospital where she died the next day.
