New kittens lured nine-year-old Savannah Grahl, her 11-year-old sister, and a friend into a barn at a farm near Eden, Wisconsin. Huge hay bales, the large rectangular ones that can weigh up to 1,000 pounds, were stacked there, but the girls knew of the danger and had been told to stay off them. In the audio below, Savannah’s mother tells WGN’s Steve Alexander the harrowing story of what happened when two of the giant bales fell and pinned the child, leaving her unconscious and not breathing. Agricultural work sites are among America’s most dangerous and are the only ones where children of all ages are routinely present. The National Children’s Center for Rural and Agricultural Health and Safety in Marshfield, Wisconsin, reports that on average, a child dies in an agriculture-related incident every three days in the US, and each day, at least 33 children are injured.
