Nothing is known about this woman's life before or as the outbreak began.
This woman was not included in the Woodbury army and remained behind in the town. She was taken to the prison with the other residents and joined the prison community.
This woman was sleeping in Cell Block D until she was infected by Patrick and turned into a zombie. She stumbled out of her cell and was subsequently shot by a fellow survivor wielding a shotgun. The gunshot did not kill her, and she proceeded to attack Ryan Samuels, who tried to defend himself by repeatedly hitting her with a brick. She bit Ryan twice, which would then lead to his death. She was put down by Glenn, who stabbed her in the head with a machete.
Sometime later, she is buried in the prison yard with the other deceased residents.
This list shows the victims this woman has killed:
- "Prey" (No Lines)
- "Infected" (Zombified)
- Originally, Abigail's character was going to be left assumed dead, similar to the rest of the Woodbury townspeople, regardless whether they appeared for the massacre scene or not in "Welcome to the Tombs". However, they brought her back after she attended the Zombie School led by Greg Nicotero, and brought her in as a Woodbury refugee only to be infected and turned into a zombie.
- While unnamed, Abigail's character was referred to as the "Gun Shot Victim" walker in the episode script.
- Her death was featured as the "Kill of the Week" on Talking Dead for "Infected".
- Abigail Jackson also portrayed a separate walker outside the fence in "30 Days Without An Accident".
