- "I'm sorry Troy. We've just been thinking-- (...) This is what we put in. Following the rules here."
- —Dax to Troy.[src]
Nothing is known about Dax's life before the apocalypse except that he had a mother, Pat and a sister, Charlene.
Dax and his mother Pat attempt to remove supplies from the armory and are stopped by Troy. Pat informs Troy that Jeremiah gave them permission to remove what's theirs as they plan to leave the ranch. After learning that the Trimbol family was slaughtered, he decides to stay on the ranch and returns the supplies to the armory.
At night, he is with the militia sympathizers and listens to Cooper as he tries to persuade Nick to stand up and lead the fight against the Natives.
Dax is among the ranchers to evacuate to the underground pantry. As Alicia addresses the crowd about those who were bitten, he is among those to come forward regarding his bite, despite his mother's pleas. Ultimately, he is put down and killed with the other bitten victims.
- Killed By
- Troy Otto (Caused)
Troy secretly redirects a massive horde of walkers towards the ranch. When the horde gets to the ranch and attack everyone, the remaining survivors enter the pantry.
- Blake Sarno (Caused)
Since the air vent is locked, Blake suggests that they put down the bitten survivors in order to preserve the air.
Dax is among the bitten survivors to step forward and to be stabbed in the head by Alicia to prevent reanimation.
This list shows the victims Dax has killed:
- Himself (Sacrifice)
- Possibly numerous counts of zombies
