He's in (enemy computers)
In a few hours after Tristan got the flash drive, the video infected with the trojan was sent to Dagoberto Quixada's secretary and adviser.
He watched it from his work computer and immediately wanted to show it to more people. He wasn't in his position because he was a tattletale, though, so instead he only forwarded the message to Quixada's email.
At the time, Quixada was inspecting the soldiers that were preparing for the next stage of the street war between the gangs. An hour later, he watched the video from his smartphone while his bodyguard drove him back to his mansion.
After hearing the insulting words of Leon Clavon, Quixada gripped the smartphone and almost chucked it through the car's window on the spot!
<That arrogant goat! He tries to provoke me again?! Well, he shouldn't have poked a dormant volcano. Hey, drive faster! I want be in my office five minutes ago!>
