Bob King was waiting in the car for his wife, Jenny, to come back from a church event when the doors inexplicably locked. In poor health, the 68-year-old couldn't push the door open.
The Kings always had problems with the door, but this time it was more than an inconvenience. The day was sweltering in Knoxville, Tenn., and the temperature in the car would soon top 120 degrees.
Thankfully, King can look back on the mishap today, all thanks to a hero who walked by at the last minute, 3-year-old Keith Williams. This ABC News report tells the story of how little Keith and his pastor saved Bob King's life that hot day in Knoxville.
