Nothing is known about Sgt. Czarnecki prior to the apocalypse, other than that he was part of the US military.
Sgt. Czarnecki is mildly seen in the background of this episode.
Sgt. Czarnecki is found by Lt. Mueller. Mueller shoots Czarnecki in the head, thinking he has given mercy to him. Mueller is incorrect and Czarnecki is seen getting up in the background, and Mueller is killed off-screen.
