Answer:
The bank cannot actually stop payment on a cashier's check. It is obligated to pay it if presented by the payee or a holder in due course. In this case, the bank had no defense against paying the check.
The most the bank might have done (and neither of us was there to know the circumstances at the time of presentment) is to contact the police in the hope of having them capture the thief in the act of cashing the check or exiting the bank. Apparently, the bank did not do this.
