I agree with Ed. There is not enough information to determine whether an SAR should be filed. BC has offered some practical advice. Look for an internet footprint on the beneficiary or the address listed in the wire. More importantly, how was the wire funded? Have the funds been there for a while or did the customer make a recent deposit and then wire out the funds?
At the end of the day, you should reach out the customer and ask. There could very well be a reasonable answer to this.
