He exited his truck and was walking toward the travel center near the fuel island when another tractor-trailer, running him over, was traveling through the parking lot and struck Mr. Clark. The truck driver parked his truck at the fuel island and went into the store for approximately twenty minutes. When he made it out to his truck, he was notified by other drivers that he may have possibly run over Mr. Clark. He got back into his truck and drove out of the parking lot.
