Almost nothing is known about Michelle's life before the apocalypse. All that's known is that she had a father and an unborn baby who died in a miscarriage.
Michelle holds Carol at gunpoint when she, along with Donnie, Paula, and Molly, ambush Carol and Maggie outside the Savior compound. They bring the women to a safe house and tie them up, waiting for reinforcements to arrive in order to prepare for a potential exchange to save Primo from Rick. At one point, Michelle is ordered to take Maggie to another room and interogate her. As she and Maggie talk, Michelle reveals that she stole from the Saviors in order to look for her boyfriend, who went missing with other Saviors. She is the one who found the remains of Bud, her boyfriend, and the other motorcyclists. As a result of her theft, she has a finger chopped off as punishment. When Maggie and Carol get the upperhand, Michelle fights with Maggie, armed with a knife. She is able to slash Maggie, hitting her belly. Startled, Michelle realizes she almost hurt Maggie's baby as Carol sneaks up on her and executes her with a gunshot to the head.
During their struggle, Michelle attacks Maggie and nearly slashes her abdomen, but Carol manages to shoot Michelle dead.
This list shows the victims Michelle has killed:
- Numerous counts of zombies and possibly unnamed people
- Michelle is the one who found the remains of Bud and his gang as she searched for her boyfriend, who is one of the Saviors blown up by Daryl's RPG in "No Way Out".
- Jeananne Goossen was so afraid of walkers that prior to shooting any scenes with walkers, she met and greeted each of the extras portraying walkers for a reminder that they were just "people in costume".
