“As the plane made its way toward the runway, one of the group’s escorts shouted that she found Inbar’s passport in another child’s backpack. ‘
How did it get there in the first place?!
Sounds like some careless adult gave the passport to the wrong kid.
Kids with cancer are just like other kids - including that some are jerks. It's possible that a kid hid her passport in his own backpack or in another kid's just to be a jerk. I wouldn't jump to the conclusion that it was an adult.
