Nothing is known about Dom's life prior to or as the outbreak began.
Dom, along with Pete, has been working at Tank Town to produce gasoline since Clayton set up the entire operation a long time ago. He works alongside Wendell, Luciana, Annie, Max, and Dylan to keep the oil production operations going when Logan and his crew suddenly arrive at the quarry. They are held at gunpoint and forced to help produce oil for Logan.
At night, when a herd swarms the quarry, Dom and the others seek refuge in their vehicles until the situation is ultimately resolved. By morning, he and the others negotiate with Logan's crew when they are suddenly sniped and killed by Virginia's army.
After a few uncertain moments, Dom and the others are released and they all re-join the caravan while Luciana stays behind to help Virginia's army produce the gas they need for their network of communities.
Dom is among the survivors traveling with the caravan in search of a permanent home. He walks about the base camp as other survivors rest while some scout nearby potential locations. After the locations are deemed uninhabitable, the caravan faces an uncertain future until that night, a walker from a Humbug's Gulch theme park 15 miles away wanders into camp. That's when the survivors get the idea to head to the Humbug's Gulch in search of a home, so Dom and the others pack up and continue their travels, despite being forced to leave several cars behind due to the gasoline shortage. The caravan runs into another issue when they come across a bridge in danger of collapsing. After several tense moments with Virginia and an oncoming herd, Dom and the others are forced to abandon the rest of their vehicles and flee across the bridge. He and the others watch in horror as Tom is killed when the bridge finally does collapse. Later, he rests with the other survivors before making the final 15 mile trek to the Humbug's Gulch, helping Pete push Wendell's wheelchair over the rough terrain. Eventually, he and the others finally reach their destination, only to witness it completely overrun with hundreds of zombies. Desperate, tired, and with no food or water, Dom and the others are forced to radio Virginia for help, facing an uncertain future.
Though unseen, Dom is among the caravan survivors to rest on the outskirts of Humbug's Gulch. After the Western-style theme park is cleared of zombies, Dom attends John and June's wedding in the chapel. That night, Dom and the caravan survivors are split up by Virginia into different groups as they are taken for re-settlement among her communities.
Dom is among the Pioneers present at Tank Town when explosions rip through the oilfield, eventually resulting in its destruction. It is unknown if Dom was killed in the attack or was among the workers able to evacuate in time.
This list shows the victims Dom has killed:
- 4 unnamed people (Possibly, Alive, Caused or Direct, Possibly Alongside Clayton and/or Pete)
- Possibly numerous counts of zombies
- Despite appearing with the rest of the group at Humbug's Gulch at the end of "Channel 5", Dom did not appear in "End of the Line". Regardless, Dom is considered still alive and still part of the group, despite the actor's unavailability to film for this episode.
