Roger DeMarco

Roger DeMarco was one of the survivors of the undead apocalypse who took refuge in a secluded shopping mall.

Roger and Peter were part of a SWAT team who are sent to attack an apartment building where the tenants are not bringing out their dead. When Wooley, one of Peter's fellow SWAT troopers, goes berserk and starts gunning down both zombies and innocent bystanders, a disgusted Roger and Peter go into the basement.

Roger and Peter agree that the zombie apocalypse will only get worse, and decide to abandon the SWAT team and join Stephen and Francine. A priest then comes in and allows Roger and Peter to "do what they must." The two then kill all the zombies kept in the building's cellar.

Roger and Peter meet up with Fran and Stephen at a deserted police station on the Delaware River in time to save the two from four rogue cops, and the four spend all night flying around in the helicopter. In the morning, they arrive at a secluded airport to refuel, and are attacked by zombies which Roger and Peter successfully kill. The group eventually reaches a secluded, zombie-infested shopping centre, where they land on the roof and break in through the skylight to rest and collect supplies. Peter and the group race around the mall, collecting supplies, which they take to a zombie-free upstairs area. When the group decides they need to clear the mall's zombie infestation, Roger and Peter go out into the zombie-infested parking lot and hotwire semi-trucks from a nearby warehouse. They use these trucks to block off the mall entrance, but while doing this, Roger becomes arrogant and reckless, and is bitten on the arm and leg.

Stephen, Fran and Peter care for the ailing Roger. While suffering a high fever, Roger promises not to come back if he dies. Hours later, after his death, Roger's corpse reanimates and gets up, forcing Peter to mercy kill him. He was later buried inside the mall by the group.
