Sero

Sero was a member of Tateos Gadjoyan's arms-dealing organization.

After Jamar Lagunov discovered that Daniel Boyce was an undercover CIA agent, he ordered Sero to have him imprisoned in a private room within one of Gadjoyan's clubs. Sero later let Gadjoyan and Lagunov into the room, where Gadjoyan interrogated and murdered the CIA agent.
