Here's the situation: Customer has a personal account, a business account, and a business loan. Customer comes in and withdraws $15,000 from his personal account and takes it over to his loan officer and tells her he wants to pay down on his loan principal. She tells him he's being silly and sends him back to redeposit the cash so she can ACH the $15,000 out of his account and apply it to the loan. He goes to a different teller, and deposits the cash into his business account (not the personal account it originally came out of), instead of going back to the same teller so he can delete the original transaction and return the unneeded cash to the vault. Neither of the two tellers knew about the other one and so didn't catch on to the foolishness. We didn't put 2 and 2 together until I looked at the CTR report the next morning. So, now I have two transactions, two accounts, and two tellers to deal with. Should I call this a wash and not file, or go ahead and file just to be safe?
