He is investigating the terrorist bombing of the Lev subway train and those connected to it. He and his agency have connected the bombing to the terrorist group Soldiers of the One (STO), linking Ben Stark to the bombing in particular. He also has a link with Zoe Graystone to the bombing beyond that of a victim, uncovering an incriminating e-mail sent to her mother Amanda Graystone seconds before the explosion that had the tone of a goodbye note. It was a goodbye note, but only to inform her parents of her running away. However, from Duram's perspective and the context of the bombing, in addition to Amanda's declaration at Apollo Park, it appears to implicate Zoe's involvement with the STO (CAP: Pilot, "Rebirth", "Reins of a Waterfall").
Pursuing that theory, Duram later uses the ensuing media attention and a sympathetic judge to secure a warrant from Inter-Colonial Court that allows him to search both the Graystone Estate and the Athena Academy for further evidence of Zoe's guilt. However, he gave credit to fellow agent Youngblood in an effort to get her back into Director Gara Singh's good graces after an earlier clerical error which indirectly allowed the bombing to occur (CAP: "Reins of a Waterfall").
Little is known about Duram's personal life other than that he has been married multiple times, and has a young son. He is also a devout polytheist, which may serve as the reason for his passionate pursuit of the STO (CAP: "Retribution," "Blowback").
