"It's definitely Barton. What he's done here, what he's been doing for the last few years... I mean the scene that he left... I gotta tell you there's part of me that doesn't even want to find him."

- James Rhodes to Natasha Romanoff

Barton used his superior skills as an assassin to infiltrate their base of operation and began to slaughter all the members ruthlessly and quickly, that the cartel could not even get the chance to draw their weapons. Barton would then leave a horrendous scene of dead bodies that would be found by the, and later James Rhodes, who was searching for him under the request of Romanoff.
