Still thinking out loud....
Okay, she gets off the bus, the truck was sitting off to the side of the road and she doesn't run up to it, so she doesn't recognize it, he follows her, pulls up beside her. If he is on the driver's side, closest to him, and he is asking for directions, the door swings out, meaning if he goes to exit the truck, she is now closest to the hood of the cab. Why doesn't she run, drop everything and take off to Grandma's house screaming....? Trucks are higher than cars too, so she would have to get close enough for him to grab her, would you do that at age 12? Stranger Danger, she is 12 she has to know not to get too close to the truck. Just throwing stuff out there to see how he got her and all her stuff into a strange truck, a man she doesn't know and no fight or screams in broad daylight. If you are fighting, you have to drop the case or the book bag, your purse. The only way I see her getting into that truck under these circumstances is if he had a gun. She was into sports, water skiing, archery ; I think she was strong enough that she put up a fight and left some marks on him. JMO
