I would think that preventing her from getting her personal property is a crime as well as the check fraud.
It wouldn't hurt to file a police report, to have the complaint on record.
Or perhaps having a registered letter sent indicating that she believes certain property, enumerated in the letter, such as her computer, and specific damages, such as NSF fees, cost of new checks for new account, etc, are due her.
It may be worth an hour of a good lawyers time to learn what her options are.
Or, perhaps a call to the local DA or PD?
You never know.
