I am on the fence with a SAR referral. We have a 21 year old college athlete who deposited approx. $12,000 in cash to her account. Clarification: my bank is in a high volume cash area (also a HIFCA). I am so used to seeing hundreds of thousands of dollars in cash that this seems like little or nothing. Other transactions on the account include cashing (depositing the checks and then withdrawing cash) of two third-party federal student loan checks. When questioned about the cash deposited, she said it was her savings. She also exchanged $1,000 in twenties for one hundred dollar bills. My initial response was to file as the activity was unusual, but after thinking about it I think we should monitor the account for another 30-90 days. My sticking point is whether or not I believe she committed a crime. I could use a sounding board so please let me know your opinions. Thanks!
