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.
This list shows the victims Dax has killed:
