account opening documents and account statements are examples of supporting documentation that can help the law enforcement agency to verify the identity, profile, and activity of the customer involved in the suspicious transaction. These documents can provide useful information such as the customer's name, address, date of birth, identification number, occupation, source of funds, transaction history, and beneficiaries. These documents can also help to establish the baseline of normal and expected activity for the customer, and to identify any deviations or anomalies that may indicate money laundering, fraud, or other criminal activities.
