Yhe checks are more than likely counterfiet. If you had deposited them. it may have cleared your bank at first but after a month the bank would have realized the checks were no good and you would have been responsibele for the full amount of the check. I would contact teh FBI about this as well as local and state law agencies. You were lucky you had second thoughts. If it seems too easy or 2 good 2 b3 true it is.
