Vikram Singh:  I was able to trace the ownership of the warehouse where Sam Mackey dropped off the heroin . It 's a Caymans shell corp . I dug back into the articles of incorporation from ' _ 99 _ . You wo n't believe who wrote up those documents . Caleb Brown .
Kate Beckett: Acosta 's public defender ?
Vikram Singh: Turns out Brown worked for a major corporate law firm back in the day . Pulled in mid - six figures annually . Then he suddenly gave it up a few years ago to be a ... defender of the people .
Kate Beckett: That 's the perfect cover . It gives Brown access to assets in prison and allows him to pass orders to dealers that we 've already caught .
Vikram Singh: Dealers like Acosta .
Kate Beckett: Brown told Acosta to take the fall for Lara 's murder so that we would back off of the drugs .
Vikram Singh: And Acosta obliged . That 's how powerful Brown is .
Kate Beckett: Okay , we ca n't go straight at this guy . He 's not a scared truck driver . This guy is a shark , and if he sees us coming , LokSat 's gon na burn all of us . We 've got to track Brown 's every move , nice and quiet .
Vikram Singh: It 's gon na take time .
Kate Beckett: Yeah , but if we do it right ... he 'll lead us straight to LokSat .
