I created a charity so that I could embezzle money from it
Don't you think that is illegal? How are you doing this?
I have found a way to avoid being caught, I make a contract with a individual who pretends to be a customer and i give her a portion of the money for acting as a customer.
You just think you've found a way to go undetected. Trust me, you're dealing with other people, someone is going to extort you and you're going to get caught.
I can't wait to see how my plan don't work against me...
You might get away with it for a while but eventually you will be audited and they truth will come out. Hiding money in a freezer or some place else will make you look even more guilty when you get caught.
