Ronald Barnes is a sociopath. An embezzler convicted of charities fraud and insider trading, he had stolen over half a billion dollars before being apprehended.
Barnes times his escape down to the second. At precisely the moment he expects, an 18-wheeler crashes through the brick wall of the prison and the chaos sends prisoners and guards flying. As the driver distracts the guards with gunfire, Barnes boards the back of the truck along with Chester Rhodes, Tran Jun, Sandy Clemente, and Carlos Zepeda. They grab a guard as a hostage, then climb into an SUV in the back of the truck and drive out through the giant hole in the wall. Later, the guard is murdered by Rhodes.
Once out, Barnes strings along his fellow cons, using their skills and connections and then leaving them for the Marshals to find, ensuring that they don't have enough information to risk him getting caught.
At one point, he and Chester Rhodes go to one of his former homes in the suburbs, where Rhodes beats an innocent man to death. Later, once he doesn't need him anymore, Barnes shoots Rhodes in cold blood and leaves him in a storage locker.
Before being caught, he holds a gun to Lloyd's head and uses him as leverage to stop Charlie and Ray from capturing him.
