It was a race against the clock to save a baby trapped inside a car in the blistering Florida sun earlier this month. Christina Tufford accidentally locked her 10-month-old daughter, Maddie, and her keys in the car in Stuart. Tufford called OnStar, but her account had expired, leaving the company with no way of unlocking the car via satellite. Ten minutes into the drama, the air conditioner automatically turned off and the temperatures inside the car started to rise.
