The information on the system was extremely simple; Diego didn't have any criminal records, not even a traffic ticket in the system—suspiciously clean, and Jimmy definitely didn't buy it.
Are there people in the United States with absolutely no criminal records? Certainly, there are many, but Diego is firstly of Mexican descent, and unless one was very wealthy during childhood, it's almost inevitable to have contact with gangs or delinquents, usually leaving some record in the police information system. Having seen too much gang information on Ruiz's side, where most of the people are more or less the same, with some records remaining, Diego, however, was exceptionally clean. Moreover, as a plastic surgeon, he was shot dead directly at home, and without any signs of burglary, it indicated that the assassin's target was him specifically, and he must have done something unforgivable. It's unrealistic for such a person to have no criminal history.
