Calvin Deets (Novel Series)

Calvin Deets is a man living in Woodbury, Georgia. He is described as an older man, an emaciated chain-smoker probably in the late stages of emphysema. He has a face like an old saddlebag left out in the sun.

Location unknown
Nothing is known about Calvin's life before the apocalypse. He could have lived in or near Woodbury, Georgia.

The Walking Dead: The Road to Woodbury
Sometime after the apocalypse began, Calvin made his way to Woodbury. There he worked with Josh Lee Hamilton and the other men. After working with Josh for several weeks, the two become good friends. After Josh is killed, he makes a coffin out of a piano case, the only container large enough to hold Josh. It takes Bob and himself hours to dig Josh's grave in the frozen ground. He later attends Josh's funeral along with Lilly Caul, Bob Stookey, Megan Lafferty, Alice, and Dr. Stevens.
