Duane Jones (Comic Series)

Duane Jones was a young boy hiding out with his father, Morgan, in various houses in Rick Grimes's neighborhood, attempting to ride out the zombie apocalypse.

After-Apocalypse
As a delirious Rick Grimes mopes about in his neighborhood, Duane hit him over the head with a shovel, and knocked him unconscious. Duane's father, Morgan, realizes Rick is human, and they take him into the house they're staying at to care for him. Duane is present during Morgan's explanation to Rick about the zombie outbreak.

After talking, Rick, Morgan, and Duane go to the police station where Rick worked. Rick gives Morgan some guns and a car, and Morgan tells Duane he plans to teach him how to use a gun, because he's old enough. Morgan and Duane plan on staying in the small town, so Rick and Morgan wish each other well and Rick mentions he will come back later for the two.

After Rick's departure, Duane and his father return to their shelter in Rick's old neighborhood. Much later, at Christmas, Morgan and Duane are seen alive and living in a cabin on a snowy mountain, in safety and relative comfort.

Killed By
Almost a year after the apocalypse, and several months after Rick left Morgan and his son, Duane was bitten and turned into a zombie. Morgan killed four men and two dogs to feed him.
 * Zombies

Months later, Rick re-encountered the two, finding Morgan still alive but Duane zombified. Rick tried to convince Morgan to kill Duane's zombie, because the real Duane was already dead. Morgan left with Rick, but instead of killing his son, he left Duane to roam freely within the house.

Morgan Jones
Being father and son, Morgan was very protective of his son even before he died. It was likely that when Duane died Morgan still had very strong feelings for his son, as shown woth Morgan's unwilllingness to kill Duane whilst he was turned.

Rick Grimes
Not much is revealed of their two relationship. Rick is still seen sad and shocked after his death. Rick didn't remember his name, and though his name was "David". He had, however, remembered it by the time he, Abraham and Carl got to Rick's neighborhood; when Morgan hit Rick in the head with a shovel, Rick spontaneously exclaimed "Duane?", only to find out it was the boy's father who attacked him this time.

Trivia

 * The name "Duane Jones" was the author's homage to the African-American actor of the same name who was the main protagonist in Night of the Living Dead (1968).
 * Duane was the first one of Jones family to reanimate as a zombie (not counting his mother, Jenny Jones, who was already zombified after the outbreak in the TV series).
