Nothing is known about Craig's life before or as the outbreak began, except that he had a brother named Ethan. He may have lived in or near the D.C. area.
When Andy arrives at the Savior outpost, he shows the head of "Gregory" in exchange for his captured friend. After the Saviors accept the gift, one of them brings out Craig, badly beaten, who is then promptly rescued by Rick's group. He rests in one of the cars with Tara, Gabriel, Andy and Jesus until the attack begins, in which he and Andy drive back to Hilltop.
This list shows the victims Craig has killed:
- Possibly numerous counts of zombies.
Craig and Ethan are never seen interacting on-screen, but it would be safe to assume they were close considering that they are brothers, their closeness is further solidified by the fact that he was willing to kill Gregory to ensure his brothers safe return. How Craig reacts upon learning of Ethan's death is unclear.
