when you say clearly he was, i think you meant clearly he was the victim. i believe he was the victim too.
According to the story from the link:
The employee who assisted him at the store took the gaming console out of a locked cabinet and told him it was previously returned, Baksht told WPTV.
The associate mentioned to him the box felt heavy, but at the time Baksht felt there was nothing strange about that since he'd never bought one before and wouldn't know how much it weighs.
so, the employee said it was a previously returned item, so Igor bought a previously returned item and the associate which i believe meant the employee said it was heavy so that must have meant the someone put rocks in it when they returned it before Igor buys it.
So like you, I believe he is the victim and innocent on this one.
