No that can't be because he already told the detectives in the recorded interview on 17th Feb 2010 that the $15K was what he owed Joey, then he was telling them that with the money due on Paul Mitchell and Saudi Arabia (26K) Joey would owe him 11K.It it isn’t clear that he is not saying Chase overpaid him. Twist it like the defense attorneys are going to. It can be twisted. IMO
So the 15K figure is Chase owing Joey and not the other way around. He just conveniently omitted to tell them about the other £27800 for Provecho and Levine that Joey added on to that figure.
