A 11-year-old boy was electrocuted while washing a horse in a barn in an unincorporated area outside New Lenox.
The boy, who was washing the animal, turned on a fan which is believed to have short-circuited, said Will County Sheriff's police spokesman Pat Barry.
An autopsy confirmed Niemeir died from electrocution.
An investigation underway considers the child's death an accident.
No charges are expected, said Barry.
