Explanation
The investigator should proceed in this situation by conducting the investigation as usual, since the activity in question is not directly connected to the PEP (A) and sending a referral to Sanctions/List Screening, or similar department/responsible individual, to ensure that the customer due diligence information is up to date (D).
These actions are appropriate and prudent, as they allow the investigator to continue their analysis of the suspicious activity without being biased by the potential PEP status of the customer's relative, and they ensure that the FI has accurate and current information about its customers and their associates. According to the ACAMS Advanced Financial Crimes Investigations Certification Study Guide1, "the FI should conduct enhanced due diligence on all parties involved in the investigation, including checking various sources of information, such as watch lists, sanctions lists, negative news, and official registries" (p. 24). The FI should also "update the customer profile with any new information obtained during the investigation" (p. 25).
The other options are not correct. The investigator should not refer the newly identified customer's account for closure due to the high risk associated with the potential PEP (B), as this could be premature or disproportionate, as well as potentially discriminatory or illegal. The investigator should not file a SAR/STR due to the potential involvement of a PEP (E), as this could also be premature or unnecessary, as well as potentially misleading or inaccurate. The investigator should not use this case as an example to train employees to recognize potential PEPs during their investigation process , as this could violate confidentiality or data protection laws, as well as compromise the investigation or alert the customer or their relative of the suspicion.

Explanation
According to U.S. law, money mules can be prosecuted even if they were unaware that money was transferred, as long as they acted with reckless disregard of the source of the funds or the purpose of the transaction1.
This is because money mules are considered to be aiding and abetting money laundering, which does not require proof of specific intent2.

Explanation
The best next step in the investigation is to check the jurisdiction's list of known charities with connections to terrorist activity . This is because the FI has a responsibility to verify the legitimacy and reputation of the beneficiary of the funds, especially if it is a charity or non-profit organization that operates in a high-risk jurisdiction or sector. According to the ACAMS Advanced Financial Crimes Investigations Certification Study Guide1, "the FI should conduct enhanced due diligence on all parties involved in the investigation, including checking various sources of information, such as watch lists, sanctions lists, negative news, and official registries" (p. 24). The FI should also check if the beneficiary is consistent with the customer's profile and expected activity.
The other options are not as appropriate or effective as option C.
Contacting the financial institution in Turkey that has a relationship with Forever Free and advising them of the investigation (A) could violate confidentiality or data protection laws, as well as compromise the investigation or alert the customer or beneficiary of the suspicion. Updating the customer profile to include Forever Free as the recipient of the funds (B) could be premature or inaccurate, as it does not verify the nature and purpose of the transfer or the identity and legitimacy of the beneficiary. Filing a SAR/STR with the new information learned about the beneficiary (D) could also be premature or incomplete, as it does not confirm if there is any suspicious or criminal activity involved in the transfer or if there are any other red flags or indicators.

Therefore, options C and D are the correct answers.
