Maybe you should read Kim's statement. In fact, why don't you?
Pay particular attention to this part, said by Kim,
"forgot to mention that the first time Precious came to the car she left because she felt there was more money to be made. It was after then, that the boys helped her to the car. They carried her by throwing her arms over their shoulders and assisting her walking to the car - I can't remember if only one boy helped or 2."
My apologies, I stand corrected...
