I filed a SAR on a customer a while back because this person was knowingly serving as a money mule.
This week I find that they are at it again, however this time they are helping facilitate some of the out of state Nigerian/unemployment fraud schemes against another state.
Typically I would wait until 90 day re-review, but given the attention these special cases have been getting (and the secret service is asking for these to be filed timely) should I file ANOTHER SAR on top of the one I just did a month ago? Should I just let it sit until the normal re-review date for this customer?

How far is "awhile back"? How much longer until the 90 day review period?
Or you could amend the previous SAR to include the newly discovered activity?

it was a month ago. I could do an amendment, hadn't done one of those in awhile tends to slip my mind. thanks

You would not amend a previous SAR for new activity outside of the time period first reported.

Financial institutions may also file SARs on continuing activity earlier than the 120-day deadline if the institution believes the activity warrants earlier review by law enforcement.

Why is this fraudster still a customer?

Great point Ed!

why was the account not closed at the point you determined the customer was KNOWINGLY engaged in fraudulent activity?

My thoughts EXACTLY Happy, I'm like they are/were still a customer after round 1 why?

The first time a money mule is found, they may be a victim in the scheme, depending on the circumstances. But the second time, they're definitely part of the problem.
