Six-year-old Karter Thorpe was sitting in the back seat as his grandma drove through a Lowe’s parking lot in Franklin, Virginia, in search of a space when he saw a man lying on the ground. The man, who was sprawled across the pavement next to a truck, started to twitch — and that’s when Karter yelled at his grandma to turn around. Grandma thought her grandson was just exaggerating. She kept on driving, but Karter wouldn’t let it go. He told grandma, “No, you have to stop! He’s hurt, he’s hurt. You have to go back!” As grandma made a U-turn she saw a pair of feet peeking out behind a truck. Sure enough, a man was lying on the ground. She pulled out her cell phone and dialed 911. Another passerby stopped and performed CPR until an ambulance arrived. The man’s family later said he’d suffered a major heart attack and would have died if it weren’t for Karter’s quick response.
