Pocono officials say two people were taken to hospitals in critical condition after Sunday's lightning strike. Track president Brandon Igdalsky confirms that one of them later died at Pocono Medical Center. He provided no details.
Track vice president Bob Pleban says five people were treated at the scene. Three others were hospitalized with moderate or minor injuries.
Pleban says it's not clear if all 10 were actually struck by lightning. It's unknown whether one or multiple lightning strikes occurred.
The race was called because of rain, with 98 of the 160 scheduled laps completed.
