A sound analyst for "ShotSeeker", a NYPD acoustic surveillance system, Garvin has a very acute sense of hearing. His investigation into the disappearance of Krupa Naik lands him in the cross-hairs of Samaritan. He is disregarded as a threat by Samaritan after Finch and Root upload Naik's research online.
He is the head of an anti-hunger non-profit called "Feed The Globe". Krupa Naik planned to license her research to them to help feed millions of people around the world, but disappeared before the deal went through. After being questioned by Detective Fusco regarding Naik's disappearance Haas pointed them to JD Carrick.
The CEO of "Harvesta", he tried to buy Krupa Naik's research outright, but she chose "Feed The Globe" over them. Samaritan framed him for the disappearance of Naik as he had a history of making his opponents disappear.
A friend and neighbor of Krupa Naik, she was in the possession of a hard drive containing Naik's research. Her number came up and she was killed by a Samaritan agent, but Root was able to recover the hard drive.
