Season 4[]

"Warren's Dream"[]

Lt. Mueller is seen consoling refugees at the camp.

"Escape from Zona"[]

During a search for the missing convoy, the group come under attack. Sgt. Czarnecki, a Marine under the lieutenant's command, is wounded and unable to be rescued; Lt. Mueller is forced to give the mercy order on his friend to prevent him from becoming a zombie. However, it doesn't kill the sergeant and the group retreats to the camp.

"The Vanishing"[]

The zombified 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 while the lieutenant is looking away; Mueller is then killed off-screen. He later returns to the camp as a zombie and attacks the group. He is then killed permanently by Pvt. Lilley.
