If the latter, and you have paperwork, you might be able to take the individual to small claims court, though if your lease prohibiting you from renting out rooms then it might get thrown out due to the intentional violation.Any time a person guarantees or co-signs (whether a lease, an auto loan, student loan, etc.), the individual needs to be ready to make the payments (remaining and any already past due). 

I recommend you do the same unless you want to encourage this tenant that it is okay to make their problems into your problems.For the future, consider requiring ACH/auto-debit/Zelle or some other form of automated/electronic payment so "I couldn't get to the bank" is no longer a factor.
