Little is known about Haley's life prior to or as the outbreak began. It is known that she owned a very expensive compound bow and her father wanted her to go to the Olympics. She also mentions having a brother.
Haley's father and brother became infected at an unknown time and she had to kill them. She eventually accepts the leadership of The Governor and accepts the job of defending the town.
Haley met Andrea while working on the wall. She told Andrea about her compound bow and how she had to kill her father and brother after they reanimated. She then attempts to kill a walker with her bow, but fails, and watches, stunned, as Andrea kills it by jumping over the wall and stabbing it with a knife. She scolds her for doing so, dismayed at her unusual behavior.
Haley found the injured guard inside a house after he was beaten by Rick's group and she called for help. She was present at the meeting in Milton's laboratory before the firefight between the Woodbury guards and Rick's group. Outside, she was ordered by The Governor to look for the attackers. After the attack, she goes to the clinic with Merle Dixon to see the wounded Governor. She is later seen at the Arena next to Milton and Andrea listening to The Governor's speech about the attack. It is unclear how she reacted towards the residents' calls for the death of the Dixon brothers.
