This is weird. In my country, if a thief sells the stolen goods, the original owner will get them back without having to pay and the person who bought them off the thief is the one who ends up paying the bill (if the thief cannot be found). This is the appropriate way to handle things because it disincentivizes buying stolen goods.

EDIT: People point out to me that this was also the case here but she wanted her computer back fast. I still don't understand why the pawn shop was allowed to keep the laptop after the discovery that it's stolen good, and how it was allowed to sell something it does not own. But I don't have the legal expertise to judge this situation, it's just confusing to me.
