Two infants were among the 24 people killed by the tornado that ripped across the Oklahoma City area this week, the Oklahoma medical examiner's office said today. The office said it has identified 23 of the 24 victims and that 10 of them were children, including seven who were killed at the Plaza Towers Elementary School. All the children have been identified, including 4-month-old Case Futrell and 7-month-old Sydnee Vargyas, who both died from head injuries. The eight other children ranged in age from 4 to 9 years old. Of those, six suffocated and two died from massive injuries.
