Employee of bank purchases multiple cashiers checks, made payable to himself and wife, with cash. None triggers CTR reporting, but over a two week period the amount is substantial (over CTR trigger). Can this be discussed with employee (by BSA Officer or President) to determine source of cash and/or if there is a reason why a SAR should NOT be filed? The filing of a SAR will NOT be mentioned to employee.

Absolutely!

I don't know a better way to investigate the source of funds than to ask the customer. They shouldn't be surprised you may need to research and document that info.

Just keep it routine and low key.

Don't forget to look at (behind the scenes) where the cash may have come from and if they (the employee) ran the transaction for themselves which should be a policy violation

If there is foul play it surpises me that the employee would obtain the official checks at the bank they work at! Then again, stupid is as stupid does! SAR for sure! Anyone observing any other "odd" behaviour by the employee? Any new cars, lifestyle changes?

I've seen many occasions where people would purchase official checks as a way to control their spending or pending a significant life event such as a home or auto purchase. I've also seen the practice used to hide money pending divorce and for tax evasion. Don't assume, get the facts.

Speaking of people doing their personal banking at the bank they work for: I heard a local story that of an employee getting terminated for reasons relating to calling in sick. Apparently, their employee checking account activity was being watched on the day they called in sick and their were debit card purchases that appeared to be shopping activity....Wow! 1984

Gee, the employee only wanted to save the bank's other employees and customers from being exposed! I guess there was no concern for the throngs at the mall!
