You need to sue the tenant. If the amount is more than $7,500 (if you're an individual and not a corporation), you'll have to sue in Superior Court.
Once you get a judgment, then you can execute on it by garnishing wages, attaching bank accounts, etc. There's no such thing as debtor's prison, so this would just be a civil suit for money.
If this tenant's got money, and assuming you have an attorney's fee clause in your lease, you should hire a lawyer to go after this deadbeat since you can add the legal fees to your claim.
