Nothing is known about Erin's life before or after the outbreak. It is possible she lived in or near Alexandria before the apocalypse.
Erin is first encountered on the porch of a home with Stacy and another woman as she talks to Carol Peletier about alternative ways of baking cookies. She is one of the residents who attendes Deanna Monroe's party, where she socializes with other residents and the new arrivals. As Sasha Williams attempts to navigate the party, she can be overheard talking to Reg Monroe about another woman and how she takes too long to read the only book her book club shares.
Erin is among the townspeople present at the community forum to discuss Rick Grimes' fate. She also witnesses the murder of Reg, which she is horrified at, and the subsequent execution of Pete Anderson.
Erin is at the pantry with Olivia, Carol, and Shelly Neudermeyer going over the food supply and gathering ingredients to prepare for dinner. Erin praises Carol for her culinary skills and agrees with her after she criticizes Shelly's smoking habit. Later, Erin is attacked by a Wolf named Aphid outside her home and her abdomen is sliced open with a machete. Carol kills Aphid immediately after, avenging her. Deeming her wounds too severe, Carol stabs Erin in the head out of mercy to prevent reanimation and her cries from attracting any nearby Wolves. As Erin lays dead in a pool of blood, Carol sits for a few moments, devastated at the loss of her friend.
This list shows the victims Erin has killed:
- Possibly a few zombies
- Aaron (Indirectly Caused)
Aaron left his backpack at Del Arno Foods, which causes to lead the wolves to Alexandria.
- Aphid (Caused)
Erin is attacked by Aphid, who slices her abdomen open.
- Carol Peletier (Out of mercy)
After Erin is wounded, Carol proceeds to stab her in the head both out of mercy and necessity.
- "Shh... Shh..."
- —Carol mercifully putting Erin down after she had been critically wounded by a wolf[src]
Erin admires Carol for her culinary skills and agrees with her after she criticizes Mrs. Nuedermeyer for smoking. When Erin is critically wounded by a wolf, she mercifully kills her and ends her suffering. Carol then begins to cry about Erin's death and the deaths of the other Alexandrians.
