@Ryuzaki_Tritium: Once it's there, there's no difference between that money and yours. That's how laundering works. They taint accounts so the money is not likely to be theirs. If it's laundry and you do not report it, you are an accessory.

@kamimatsu: Tell the bank ASAP. Then there's a record showing you aren't an accessory. Tell the police you got a suspicious deposit too. Worst case scenario then, you don't keep it. WSC if you do nothing, remember, drug trafficking is a capital offense.
