Very little is known about Callaway's life before or as the outbreak began. He earned a Parachutist Badge and held the rank Sergeant Major in the U.S. Army.
During the initial outbreak, Callaway was in King County, likely assisting his fellow soldiers and FEMA in controlling the infection. Callaway was bitten on the neck and later reanimated into a zombie.
Callaway is first seen in Hannah's neighborhood, wandering out of the woods with a group of zombies. He is walking toward Hannah, Jamie, and Billy. When Hannah backs up and sacrifices herself for her children to live, he begins to devour her along with the group of zombies.
While Otis and Shane Walsh are at a high school nearby the Greene farm, they are gathering medical supplies for a wounded Carl Grimes. When Shane tosses the flares in order to distract the zombies, Callaway is witnessed again.
Callaway is one of the zombies that follow Shane and Otis to the gym and try to attack from beneath the hail. It is also part of a group of zombies who follows Otis in the locker room. Then it is seen chasing Shane and Otis outside of the school again and then devour Otis with the other zombies.
