The anti-money laundering compliance officer for a small money transmitter has several agent locations in the same geographic area in the United States. The customers are immigrants from Country A and the majority of the funds are remitted to Country A.
In a meeting with one of the agents, it is recently discovered that two new customers have been coming in three times a week and sending funds to the same recipient in Country B.
Each cash transaction always totals exactly $8,000.

A money transmitter's nation-wide agent network remits funds to a country in Africa on behalf of an immigrant community based in the United States. A terrorist group is known to operate openly in this African country. In reviewing transaction records, the compliance officer detects a pattern where two customers together visit the same agent each week and remit the same amount of funds. $2,500, to the same recipient in the country in Africa.
What should alert the compliance officer to possible money laundering or terrorist financing activity by the two customers?

A suspicious transaction report filed on a car dealer structuring deposits initiates a criminal investigation. The dealer changes branches and begins placing transactions with a frontline employee to whom the dealer has given numerous gifts.
