The circumstantial case appears to be:
- A group of people is engaged in the same crime, using the same techniques;
- You are acting as a buyer and fence for these people; and
- They all state that you were the engineer of this criminal enterprise.
If they do decide they have enough evidence to prosecute, you should of course consult a criminal defense lawyer. Even if they can't prove you the "crimeboss", they may be able to present a compelling argument that you knowingly received and assisted in the sale of stolen merchandise.
