There is language in the SAR filing requirements that would make it seem as if a SAR would be required for this type of activiy. The specific language below makes it sound like you have to file if it was $5,000 or more and it pertains to either 1 or more of these 4 criteria regardless if there's a suspect.
3. Filing Requirements for Financial Institutions:
A financial institution must report any transaction that requires reporting under the terms of 31 CFR Chapter X if the transaction is conducted or attempted by, at, or through the financial institution and involves or aggregates at least $5,000 and the financial institution knows, suspects, or has reason to suspect that the transaction or pattern of transactions of which the transaction is a part:
A. Involves funds derived from illegal activity or is intended or conducted in order to hide or disguise funds or assets derived from illegal activity (including, without limitation, the ownership, nature, source, location, or control of such funds or assets) as part of a plan to violate or evade any Federal law or regulation or to avoid any transaction reporting requirement under Federal law or regulation;

B. Is designed, whether through structuring or other means, to evade any requirement of 31 CFR Chapter X or any other regulation promulgated under the Bank Secrecy Act, Public Law 91-508, as amended, codified at 12 U.S.C 1829b, 12 U.S.C. 1951-1959, and 31 U.S.C. 5311-5332;
C. Has no business or apparent lawful purpose or is not the sort in which the particular customer would normally be expected to engage, and the financial institution knows of no reasonable explanation for the transaction after examining the available facts, including the background and possible purpose of the transaction, or
D. Involves the use of the financial institution to facilitate criminal activity.
Wouldn't C and D apply to the situation you described? Does anyone happen to follow this guideline?.
It appears to contridict the language about the $25,000 or more with no suspect.
