Fake sublessee

A U. of I. student attempting to sublet an apartment received an email from an unknown person who said they would take the apartment. The unknown person sent the student a check for $3,850 to cover rent for the whole sublease period. The student deposited the check, and then the renter said they changed their mind and needed the money back. The student returned the money to two separate accounts, only to find out later that the original check never cleared.
